One attack usually confers prolonged immunity buy viagra sublingual 100 mg visa, although subsequent attacks (some of which may be attributable to B buy 100mg viagra sublingual visa. Cases in previously immunized adolescents and adults in countries with long-standing and successful immunization programs occur because of waning immunity and are a source of infection for non immunized young children order 100mg viagra sublingual otc. Preventive measures: 1) Immunization is the most rational approach to pertussis control; and whole-cell vaccine against pertussis (wP) has been effective in preventing pertussis for more than 40 years cheap viagra sublingual 100mg without a prescription. Educate the public, particularly parents of infants, about the dangers of whooping cough and the advantages of initiating immunization on time (between 6 weeks and 3 months depending on the country) and adhering to the immuniza- tion schedule. This continues to be important because of the wide negative publicity given to adverse reactions. In terms of severe adverse effects aP and wP vaccines appear to have the same high level of safety; reactions (local and transient systemic) are less commonly associated with aP vaccines. Similar high efficacy levels (more than 80%) occur with the best aP and wP vaccines although the level of efficacy may vary within each group. Protection is greater against severe disease and begins to wane after about 5 years. Although the use of aP vaccines is less commonly associ- ated with local and systemic reactions such as fever, price considerations affect their use and wP vaccines are the vaccines of choice for most developing countries. In countries where immunization programs have considerably reduced pertussis incidence, a booster dose approximately one year after the primary series is warranted. Vaccines containing wP are not recom- mended after the seventh birthday since local reactions may be increased in older children and adults. Formulations of acellular pertussis vaccine for use in adolescents and adults have been licensed and are available in several countries. Minor adverse reactions such as local redness and swelling, fever and agitation often occur after immunization with wP vaccine (1 in 2–10). Prolonged crying and febrile seizures are less common ( 1 in 100); hypotonic-hyporesponsive epi- sodes are rare ( 1 in 2000). The only true contraindication to immunization with aP or wP is an anaphylactic reaction to a previous dose or to any constituent of the vaccine. In young infants with suspected evolving and progressive neurological disease, immunization may be delayed for some months to permit diagnosis in order to avoid possible confusion about the cause of symptoms. Clarithromycin and azithromy- cin are expensive but better tolerated alternatives. Suspected cases should be removed from the presence of young children and infants, especially nonimmunized infants, until the patients have received at least 5 days of a minimum 7-day course of antibiotics. Suspected cases who do not receive antibiotics should be isolated for 3 weeks after onset of paroxysmal cough or till the end of cough, whichever comes first. Passive immu- nization has not been demonstrated to be effective and there is no product currently commercially available. The initiation of active immunization following recent exposure is not effective against infection but should be undertaken to protect the child against further exposure in case it has not been infected. A 7-day course of erythromycin, clarithromycin or azithromy- cin for household and other close contacts, regardless of immunization status and age, is recommended for house- holds where there is a child under 1. Prophylactic antibio- therapy in the early incubation period may prevent disease, but difficulties of early diagnosis, costs involved and con- cerns related to the occurrence of drug resistance all limit prophylactic treatment to selected individual conditions: - children under 1 year and pregnant women in the last 3 weeks of pregnancy (because of the risk of transmission to the newborn); - stopping infection among household members, particularly if there are children aged under 1 and pregnant women in the last 3 weeks of pregnancy. Epidemic measures: A search for unrecognized and unre- ported cases may be indicated to protect preschool children from exposure and to ensure adequate preventive measures for exposed children under 7. Accelerated immunization, with the first dose at 4–6 weeks of age and the second and third doses at 4-week intervals, may be indicated; immunizations should be completed for those whose schedule is incomplete. Disaster implications: Pertussis is a potential problem if introduced into crowded refugee camps with many non-immu- nized children. International measures: Ensure completion of primary immu- nization of infants and young children before they travel to other countries; review need for a booster dose. A scaling painless papule with satellite lymphadenopathy ap- pears 1–8 weeks after infection, usually on the hands, legs or dorsum of the feet. Within 3–12 months a maculopapular, erythematous secondary rash appears and may evolve into tertiary splotches of altered (dyschro- mic) skin pigmentation of variable size. These treponema-containing macules pass through stages of blue to violet to brown pigmentation, finally becoming treponema-free depigmented (achromic) scars. Lesions coexist at different stages of evolution and are most common on the face and extremities. Serological tests for syphilis usually become reactive before or during the secondary rash and thereafter behave as in venereal syphilis. Occurrence—Found only among isolated rural populations living under crowded unhygienic conditions in the American tropics. Mode of transmission—Presumably person-to-person through di- rect and prolonged contact with initial and early dyschromic skin lesions. The location of primary lesions suggests that trauma provides a portal of entry; lesions in children occur in those body areas most scratched. Various biting and sucking arthropods, especially blackflies, are suspected but are not proven as biological vectors. Period of communicability—Unknown; potentially communica- ble while dyschromic skin lesions are active, sometimes for many years. Not highly contagious; several years of intimate contact may be necessary for transmission. Preventive measures: Those applicable to other nonvenereal treponematoses apply to pinta; see Yaws, 9A. Control of patient, contacts and the immediate environment: 1) Report to local health authority: In selected endemic areas; in most countries, not a reportable disease, Class 3 (see Report- ing). Epidemic measures, Disaster implications and International measures: See Yaws, C, D and E. Identification—A specific zoonosis involving rodents and their fleas, which transfer the bacterial infection to various animals and to people. Initial signs and symptoms may be nonspecific with fever, chills, malaise, myalgia, nausea, prostration, sore throat and headache. Lymph- adenitis often develops in those lymph nodes that drain the site of the bite, where there may be an initial lesion. This is bubonic plague, and it occurs more often (90%) in lymph nodes in the inguinal area and less commonly in those in the axillary and cervical areas. All forms, including instances in which lymphadenopathy is not apparent, may progress to septicemic plague with bloodstream dissemination to diverse parts of the body that include the meninges. Secondary involvement of the lungs results in pneumo- nia; mediastinitis or pleural effusion may develop. Secondary pneumonic plague is of special significance, since respiratory droplets may serve as the source of person-to-person transfer with resultant primary pneumonic or pharyngeal plague; this can lead to localized outbreaks or devastating epidemics. Though naturally acquired plague usually presents as bubonic plague, purposeful aerosol dissemination as a result of deliberate use would be manifest primarily as pneumonic plague. Plague organisms have been recovered from throat cultures of asymptom- atic contacts of pneumonic plague patients. Modern therapy mark- edly reduces fatality from bubonic plague; pneumonic and septicemic plague also respond if recognized and treated early. However, one report stated that patients who had not received adequate therapy for primary pneumonic plague within 18 hours after onset of respiratory symptoms were less likely to survive. Slow growth of the organism at normal incubation temperatures may lead to misiden- tification by automated systems. Occurrence—Plague continues to be a threat because of vast areas of persistent wild rodent infection; contact of wild rodents with domestic rats occurs frequently in some enzootic areas. While urban plague has been controlled in most of the world, human plague has occurred in the 1990s in several African countries that include Botswana, the Demo- cratic Republic of the Congo, Kenya, Madagascar, Malawi, Mozambique, the United Republic of Tanzania, Uganda, Zambia and Zimbabwe. Plague is endemic in China, India, Lao People’s Democratic Republic, Mongolia, Myanmar and Viet Nam. In the Americas, foci in northeastern Brazil and the Andean region (Brazil, Ecuador and Peru) continue to produce sporadic cases and occasional outbreaks including an outbreak of pneu- monic plague in Ecuador in 1998. Reservoir—Wild rodents (especially ground squirrels) are the nat- ural vertebrate reservoir of plague. Lagomorphs (rabbits and hares), wild carnivores and domestic cats may also be a source of infection to people. Mode of transmission—Naturally acquired plague in people oc- curs as a result of human intrusion into the zoonotic (also termed sylvatic or rural) cycle during or following an epizootic, or by the entry of sylvatic rodents or their infected fleas into human habitat; infection in commensal rodents and their fleas may result in a domestic rat epizootic and flea-borne epidemics of bubonic plague. Domestic pets, particularly house cats and dogs, may carry plague infected wild rodent fleas into homes, and cats may occasionally transmit infection through bites, scratches or respiratory droplets; cats develop plague abscesses that have been a source of infection to veterinary personnel. The most frequent source of exposure that results in human disease worldwide has been the bite of infected fleas (especially Xenopsylla cheopis, the oriental rat flea). Person-to- person transmission by Pulex irritans fleas (“human” flea), is presumed to be important in the Andean region of South America and in other places where plague occurs and this flea is abundant in homes or on domestic animals. Certain occupations and lifestyles (including hunting, trapping, cat ownership and rural residence) carry an increased risk of exposure. In the case of deliberate use plague bacilli would possibly be transmitted as an aerosol. Incubation period—From 1 to 7 days; may be a few days longer in those immunized who develop illness. Period of communicability—Fleas may remain infective for months under suitable conditions of temperature and humidity. Bubonic plague is not usually transmitted directly unless there is contact with pus from suppurating buboes. Pneumonic plague may be highly communica- ble under appropriate climatic conditions; overcrowding facilitates trans- mission. Preventive measures: The basic objective is to reduce the likelihood of people being bitten by infected fleas, having direct contact with infective tissues and exudates, or of being exposed to patients with pneumonic plague. In sylvatic or rural plague areas, the public should be advised to use insect repellents and warned not to camp near rodent burrows and to avoid handling of rodents, but to report dead or sick animals to health authorities or park rangers. Dogs and cats in such areas should be protected periodically with appropriate insecticides. Rat suppression by poisoning (see 9B6) may be necessary to augment basic environmental sanitation measures; rat control should always be preceded by measures to control fleas. Collection and testing of fleas from wild rodents and their nests or burrows may also be appropriate. After the third booster dose, the intervals can be extended to every 1 to 2 years. Immunization of visitors to epidemic localities and of laboratory and fieldworkers han- dling plague bacilli or infected animals is justifiable but should not be relied upon as the sole preventive measure; routine immunization is not indicated for most persons resident in enzootic areas. Live attenuated vaccines are used in some countries; they may produce more adverse reactions, without evidence that they are more protective. Control of patient, contacts and the immediate environment: 1) Report to local health authority: Case report of suspected and confirmed cases universally required by International Health Regulations, Class 1 (see Reporting). Because of the rarity of naturally acquired primary plague pneumonia, even a single case should initiate prompt suspicion by both public health and law enforcement authorities of deliberate use. For patients with bubonic plague (if there is no cough and the chest X-ray is negative) drainage and secretion precau- tions are indicated for 48 hours after start of effective treatment.

It was most common in homosexuals, drug addicts and the recipients of contaminated blood in the form of transfusions or concentrates, but is now spreading via heterosexual contact. The virus incapacitates the T-helper lympho- cytes and thus prevents proper functioning of the cell-mediated immune response. It uses the T4 antigen as its receptor and employs the T-cell’s genomic apparatus to replicate, destroying the cell as it does so. It can also infect reticuloendothelial cells (including Langerhans cells) and B-cell lymphocytes. After gaining access, the virus usually stays latent for long periods, but may cause a systemic illness a relatively short time after infection and before or at the time of seroconversion. This illness is characterized by pyrexia, malaise and a rash, which have been described as resembling infectious mononucleosis. For the most part, there are no symptoms for several years, even after an antibody response develops, until the virus is ‘activated’ by an intercurrent infection such as herpes simplex. Systemic spread of Candida infection is unfortunately not uncommon and often a terminal event. It may also be responsible for a troublesome and persistent truncal fol- liculitis in some patients (Fig. Various ‘deep fungus’ infections are common, particularly in hot and humid parts of the world. Mollusca contagiosa lesions may be both larger than usual and present in very large numbers (Fig. It may look unlike ‘ordinary’ herpes zoster and may cause considerable pain and tissue destruction as well as spreading outside the dermatomes in which it began. Infections with mycobacterial species that do not generally infect humans may also be seen. Epithelioid angiomatosis is due to infection with a bacterial micro-organism similar to the bacillus causing ‘cat scratch’ disease. It causes Kaposi’s sarcoma-like lesions (see below) and a widespread eruption of red papules. Skin cancers Depressed delayed hypersensitivity also results in failure of ‘immune surveillance’ and the development and rapid progression of many forms of skin cancer. Mauve, red, purple or brown macules, nodules or plaques may ulcerate and may spread to involve the viscera. Case 6 Simon’s dandruff gradually worsened and he developed seborrhoeic dermatitis of the skin around his ears and nose. At the age of 23, he was surprised that he was also developing numerous viral warts and mollusca contagiosa. Psoriasis Pre-existing psoriasis may develop an ‘explosive phase’, or psoriasis may develop de novo as an aggressive, rapidly spreading eruption. Other drugs that are sometimes used include lamivudine, nevirapine, stavudine, delavudine and efavirenz. Various antibiotics and other antimicrobials are used as indicated for the bacterial infections. Fluconazole, itraconazole and ketoconazole are particularly useful for the serious and life- threatening Candida infections. Recombinant interferon-alpha 2B and other inter- ferons have been used with some success in Kaposi’s sarcoma. The new retinoid tagretin is used topically to induce regression in individual lesions. Drug-induced immunodeficiency Patients who have organ transplants of kidneys, heart or liver are maintained on corticosteroids and azathioprine, cyclosporin or tacrolimus for the rest of their lives. Patients with autoimmune disorders such as systemic lupus erythematosus, rheumatoid arthritis or chronic renal disease, and those with psoriasis and some eczematous diseases, are also treated with immunosuppressive drugs for varying lengths of time. Patients with renal allografts have most problems, maybe because they are treated continuously for longer periods than most of the other groups. They are prone to the development of numerous warty lesions on the hands and face – after about 8 years of immunosuppression some 25 per cent were found to have warty lesions in one British study (Fig. These are either viral warts or solar keratoses, or lesions which are somewhere in between! It may be that many of the viral warts directly transform into pre-neoplastic lesions. Other causes of acquired immunodeficiency Lymphoreticular diseases such as Hodgkin’s disease, the leukaemias and sarcoidosis also result in depressed delayed hypersensitivity. Hypovitaminosis A, chronic mal- nutrition and chronic alcoholism also result in depressed immune defences. Congenital immunodeficiencies Infantile agammaglobulinaemia is inherited as an X-linked recessive disorder. There are no plasma cells in the marrow and the patients are susceptible to severe pyoderma and numerous warts. In severe combined immunodeficiency, there is depression of circulating lymphocytes and levels of all immunoglobulins. Patients are susceptible to all infections and usually die between the ages of 1 and 2 years. It is inherited as either a sex-linked recessive or an autosomal recessive characteristic. Ataxia telangiectasia (autosomal recessive) is characterized by cerebellar degener- ation, telangiectasia on exposed skin developing progressively, lymphopenia and depressed levels of IgA. Such disorders include genital warts, molluscum contagio- sum, scabies and pubic lice. There is usually an accompanying arthritis and spondylitis and occasion- ally a conjunctivitis. These are often severe, persistent, aggressive and pustular (keratoderma blenorrhagica). Inflamed, red, scaling patches may also develop on the glans penis (circinate bal- anitis). The skin is only affected during gonococcaemia, when small purpuric and pustular vasculitic lesions suddenly appear in the course of a pyrexal illness (Fig. Other sites may be affected, and inguinal adenitis occurs in 50 per cent of patients. Differential diagnosis includes syphilitic chancre, herpetic ulceration, granu- loma inguinale and the results of trauma. The disease is caused by the delicate spirochaetal micro-organism Treponema pallidum, which is transmitted by contact between mucosal surfaces. Clinical features Characteristically, the incubation period is 9–90 days and the first sign is the appearance of the chancre at the site of inoculation, usually on the glans penis, prepuce or, less often, on the shaft in men and on the vulva in women. This primary stage of the disease is followed by a brief quiescent phase of from 2 months to up to 3 years before the secondary stage occurs. In secondary syphilis there are signs of systemic upset with mild fever, headache, mild arthralgia, gener- alized lymphadenopathy and skin manifestations, including an early widespread macular rash, involving the palms (Fig. Thickened, warty areas (condylomalata) appear perianally and in other moist flexural sites (Fig. The tertiary stage takes protean forms and includes cardiovascular disease with aneurysm formation, central nervous dis- order, either as tabes dorsalis or general paralysis of the insane, and ulcerative or gummatous lesions that may occur on the skin or on mucosal surfaces. Diagnosis Diagnosis is made by identification of the spirochaete from wet preparations of the chancre or moist secondary-stage lesions and by serological tests detecting either lipoidal substance liberated by tissues or the presence of antibodies to the micro- organism. It also responds to effective treatment by becoming negative some 6 months after therapy. The Treponema pallidum haemagglutination assay is currently the most-used specific test depending on antibodies to the micro-organism. A proportion of patients develop a fever and possibly a rash after starting treatment (Jarisch–Herxheimer reaction). It is characterized by depressed ● Purpuric pustules are a vasculitic complication of delayed hypersensitivity and susceptibility to many gonorrhoea and gonococcaemia. Seborrhoeic dermatitis, pruritic folliculitis ● Syphilis caused by Treponema pallidum is spread by and Kaposi’s sarcoma are other skin disorders sexual contact. Steroids and immunosuppressive erosion, the primary chancre, occurs at the site of drugs result in immunosuppression, and depressed inoculation. In some cases, immunodeficiency is in which a destructive inflammation affects one or inherited. Inflammatory cells and vasodilatation accompany the oedema that is also present in the dermis of the affected area. Some types of eczema stem from uncharacterized constitutional factors (‘endogenous’ or constitutional eczema), whereas others are the result of an exter- nal injury of some sort. The clinical picture varies according to the provocation, the acuity of the process and the site of the involvement. The patient is constantly itchy and restless, but subject to irregular episodes of intense and quite disabling intensification of the pruritus. The itchiness is made worse by changes in tempera- ture, by rough clothing (such as woollens) and by sundry other minor environ- mental alterations. Scratching results from the severe pruritus in all except infants under the age of 2 months. Patients also rub the affected itching parts – they frequently rub their eyes with the index finger knuckles (Fig. The incessant scratching and rubbing result in simple, linear scratch marks (excoriations: Fig. This is due to massive epi- (lichenification) due to dermal hypertrophy as well as oedema and inflammatory cell infiltrate in the perpetual rubbing and upper dermis (Fig. In many patients, there is a widespread fine scaling of the skin, described as ‘dryness’ or xeroderma, sometimes described incorrectly as ichthyosis, but really the result of the eczematous process itself.

In addition, anterolisthesis at the same level is noted and the anteroposterior diameter of the vertebral body. If the area of the dural sac is below 75 mm2, the likelihood of a stenosis is high. The lateral recess is bordered posteriorly by the su- perior articular facet, laterally by the pedicle and anteri- orly by the vertebral body and disk. Lumbar lateral recess stenosis occurs when a hypertrophic superior facet en- croaches on the recess, often in combination with nar- rowing due to a bulging disk and osteophyte. Foraminal stenosis occurs when a hypertrophic facet, vertebral-body osteophyte, or bulging disk narrows the neural foramen Fig. A 68-year-old woman with clinical symptoms of cervical and encroaches on the nerve roots.

And he went a little farther discount viagra sublingual 100mg on-line, and fell on his face discount viagra sublingual 100mg otc, and prayed buy viagra sublingual 100mg low cost, saying purchase viagra sublingual 100 mg otc, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt. And he cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with me one hour? Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak. He went away again the second time, and prayed, saying, O my Father, if this cup may not pass away from me, except I drink it, thy will be done. And he left them, and went away again, and prayed the third time, saying the same words. Let it roll around in your soul and sink deeply into your spirit: Saying—the—same— words. Was it not Jesus who told us that we are not to use vain repetitions when we pray? Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him. An example would be if a person flipped through a catalogue of prayers and chose one to offer to a deity. If you want to see excellent examples of genuine, heart-felt prayers, read the Psalms. The second mistake the heathen made in their praying was they thought the repetition of these template prayers would assure an answer. The power is not in the number of times a prayer is offered or in the method in which a prayer is offered. Instead He revealed that our faith should be in the Person to whom we pray, and in particular His relationship to us as Father. This is communicated when He said, “Be ye not therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him. However, unlike the heathen who offered secondhand prayers to their deity, Jesus offered prayers that came from His own heart. Second, Jesus prayed for the same thing, using the same words, not because He felt He was not being heard, but—and don’t miss this—because He knew He was being heard. The truth of the matter is that many people who pray for a thing once and don’t pray for it again, do so because they don’t believe their prayers are actually being heard. They stop praying for their item of interest because either their faith in God or their desire for the item is weak. Since Jesus knew that God was actually listening to His prayers, this encouraged Him to keep praying. Jesus prayed more than once for the same thing because He had an incredibly strong desire to receive that for which He was praying. Fourth, Jesus prayed several times for the same thing because what He was praying for did not arrive the first time He prayed. They listen to the testimonies of some who swear that they prayed once and received all their hearts’ desire. This truth is that it is not unbelief to persistently pray for something that we have already received by faith. It is because the very meaning of receiving by faith means we have not yet received it as a physical reality. This is clearly seen in the very scripture that many people use to justify acting as though a future blessing is a literal, present possession. Also, notice that this verse clearly makes a difference in “believing you receive them” and “you shall have them. If a person believes what the Bible says about God, and His great desire to heal the sick, and if that person is convinced that God will answer his prayer for healing, and offers that prayer, he is on good, safe ground. Yet if that person does this, and then literally behaves as though the answer has been received, that person may hurt himself. For instance, a person with diabetes may pray for healing and receive it by faith. This is good if the person has a proper understanding of what it means to receive healing by faith. He understands that if the healing doesn’t immediately or shortly manifest, he must act in wisdom and not presumption. Wisdom would continue to take medication until the literal arrival of the healing. Wisdom would understand that since the healing has not physically arrived yet, it can’t be physically enjoyed yet. Presumption would throw away the medication before the literal arrival of the healing. Presumption would seek to enjoy the healing before there is an actual manifestation of the healing. When the strength did not come, He could have tried to ignore the natural truth that He had not yet been sufficiently strengthened. Because a blessing that is on the way is not the same as a blessing that has arrived. Similarly, a healing that is on the way is not the same as a healing that has arrived. Therefore, Jesus continued to pray until He felt in His mind and heart a literal infusion of mental and spiritual strength to finish the job of purchasing salvation through His death on the cross. Jesus Prays for the Blind Man Twice There is a scripture in Mark that totally destroys the unscriptural belief that it is wrong to pray for something more than once. It reads: “And he cometh to Bethsaida; and they bring a blind man unto him, and besought him to touch him. And he took the blind man by the hand, and led him out of the town; and when he had spit on his eyes, and put his hands upon him, he asked him if he saw ought. After that he put his hands again upon his eyes, and made him look up: and he was restored, and saw every man clearly. It is hard for some of us to accept the fact that the blindness didn’t leave the man the first time Jesus laid hands on him. If Jesus Christ, the Almighty God and Creator of all that is, could meet such stiff resistance (in His earthly ministry), what makes us think that we will not meet the same resistance? Unfortunately, had this been a present day healing meeting, the odds are that the man would have been scolded for having a lack of faith or hiding some secret sin. However, I believe that although lack of faith and secret sins are legitimate obstacles to healing, they are not our greatest obstacles to healing. As I stated earlier, often our greatest obstacles in healing and deliverance meetings are the ministers conducting the meetings. Jesus came on the scene and scolded the apostles (not the father or the boy) for their lack of faith, prayer, and fasting. I believe He is still rebuking us ministers for our lack of faith, prayer, and fasting. Nonetheless, in the meanwhile desperate people are needlessly suffering from our lack of spirituality. First, unlike other blind people who aggressively cried out to Jesus for healing, there is no record of this man even asking to be healed. In my own ministry I have found that it is usually difficult to help people who don’t show initiative or desperation. Second, Jesus took the blind man out of town, then spit on the man’s eyes and laid his hands on him. We also must have the kind of love that will compel us to go out of our way to bring healing and deliverance to people. This kind of love sees nothing wrong with praying for people more than once for the same thing. Certainly if Jesus Christ prays for the same thing more than once, we should do the same. For if we do not, many of our prayers will never be answered—no matter how critical or desperate our need may be. The Parable of the Persistent Widow My final example of the overwhelming power of persistent prayer is in Luke 18. You should read both of them often to gain strength while you await the literal arrival of your healing (if you don’t get an immediate healing). And he would not for a while: but afterward he said within himself, Though I fear not God, nor regard man; Yet because this widow troubleth me, I will avenge her, lest by her continual coming she weary me. And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? Jesus begins by saying that His reason for teaching this parable is that we will learn “always to pray, and not to faint. But finally the woman’s persistence wears down the unjust judge and he does what is right. Jesus uses the story to graphically teach us to hold on in prayer until the answer comes. There can be any number of reasons why your answer hasn’t literally arrived yet: • It may be God testing your faith. The point is that if there is a delay to your healing, there could be one or more reasons why this is so. But despite what the reason for the delay, persistence in prayer can win the victory. For God’s promise in the parable is: “And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them? A Final Example of Persistent Prayer The Lord has been so extremely gracious to allow such a weakling like me (sorry, my faith- confession buddies) to partake in His healing and deliverance ministry. Whenever I am privileged to witness God’s mighty power set someone free of a life-long bondage or sickness, I am utterly amazed. What grace and mercy that God should use my feeble efforts as a tool to demonstrate the resurrection of Jesus Christ, and to show supernatural compassion to His people! I see a common thread as I look back over the many times I or a team member has successfully ministered God’s mighty power in healing and deliverance. Although we have had some truly instantaneous miracles occur, it seems that the great majority of our miracles have come as a direct result of persistence. Many years ago, some friends and I went to a gospel meeting where there was a large number of sick people present. I was very disappointed that aggressive prayers of faith weren’t offered for the sick. As we were leaving the stadium I noticed a terribly crippled old woman walking with two other people. As someone led us in prayer, I couldn’t get my mind off of the old crippled woman. I felt that a golden opportunity to see God’s mighty power displayed was slipping by me. While the others prayed, I got out of the car and approached the car that the old lady had entered. Since we were in the stadium parking lot and the meeting had just ended, hundreds of people were going to their cars.
