Testing Prayer: Can Science Prove the Healing Power of Prayer?

Posted: 03/02/2012 2:09 pm

When sickness strikes, people around the world pray for healing. Many of the faithful claim that prayer has cured them of blindness, deafness and metastasized cancers, and some believe they have been resurrected from the dead.

Can, and should, science test such claims? A number of scientists say no, concerned that empirical studies of prayer will be misused to advance religious agendas. And some religious practitioners agree with this restraint, worrying that scientific testing could undermine faith.

If prayer affects health -- for better or for worse -- then patients, doctors and policymakers should all want to know. Scientific research has returned mixed results. Some studies conclude that prayer improves health, while others show no effect -- or suggest that prayer may lead to worsening health.

Part of the confusion stems from how prayer is studied. Most research is on distant intercessory prayer. Intercessors are given the first name and condition of someone they do not know and told to pray. Researchers set up double-blinded trials -- because this is how they are accustomed to studying health interventions -- and base conclusions on the efficacy of prayer solely on whether subjects in the experimental group exhibit better health than those in the control group.

But when people actually pray for healing, they usually get up close to someone they know, touch the person and empathize with their sufferings -- what I call proximal intercessory prayer, or PIP. Double-blinded, controlled trials are not the only -- or even the best -- way to gauge the effects of this kind of prayer practice.

I have spent the past eight years studying PIP by Pentecostal and Charismatic Christians -- the groups most likely to pray for healing and claim that their prayers work -- in the United States, Canada, Brazil and Mozambique. And I used multiple methods, each one suited to answering a particular question about prayer for healing. Each method is like a different type of camera, offering complementary perspectives on how prayer affects health.

Camera 1: Medical Records: Are healing claims documented?

Comparison of medical records from before and after prayer provides a check on whether people claiming healing exhibited improvements for which there is no obvious explanation. For example, in the course of my research, I met Daisy, who had worn hearing aids for 30 years. She had a progressively worsening, hereditary inner-ear problem. In 1999, tests showed moderate hearing loss; by 2004, Daisy's hearing loss was moderately severe to severe. In 2008, Daisy received PIP and "felt my fingers on fire and the warmth of the Holy Spirit inside of me," after which she could hear without hearing aids. She had her hearing retested two weeks later, showing normal thresholds in lower frequencies with moderate loss in higher frequencies. A 2010 screening still showed normal hearing in speech frequencies. Medical records do not prove that "God" healed Daisy through prayer, but do confirm Daisy's claim of improved hearing.

I also came across Frank, who claimed improved vision after prayer. He produced an optometrist's note stating that "On 02" his left eye uncorrected visual acuity was "20/200"; in 2007, it was "NOW 20/40." I followed up with Frank's optometrist, who revealed that the record had been "altered." The phrases "On 02" and "Now 20/40" had been added. The unaltered record shows visual acuity of 20/200 in 2007 -- after Frank's supposed healing. Such cases of apparent fraud do not seem to be common, but medical records are one way of sifting out which claims are less credible.

Camera 2: Surveys: How do sufferers perceive healing prayer?

Surveys shed light on how supplicants perceive sickness, prayer and healing. In one set of surveys I carried out, 72 percent of respondents had a current need for healing; the most common complaint was pain. Fifty-two percent reported healing. Few "claimed healing by faith," instead defining healing as noticeable improvement of symptoms. Those who self-reported high faith were no more likely to experience healing than those who admitted weak faith. Most received multiple prayers for the same problem, noting progressive improvements with each prayer. Most also went to doctors, viewing prayer and medicine as complementary.

Camera 3: Clinical Trials: Can health outcomes of prayer be measured?

Clinical trials can show whether PIP results in measurable changes in health markers. In a prospective study of hearing and vision in Mozambique, I found highly significant improvements in hearing and statistically significant improvements in vision following PIP. Two of 11 hearing subjects had thresholds reduced by over 50 dBHL. One subject, Jordan, was presented as deaf and mute since birth and made no responses to sounds at 100 dBHL; after PIP, he responded to 60 dBHL tones, imitating sounds in a hoarse, raspy voice. Three of 11 vision subjects improved from 20/400 or worse to 20/80 or better. Before prayer, Maryam could not count fingers from one foot away; after one minute of PIP, she was reading the 20/125 line on a vision chart.

Camera 4: Follow-up: Do healing experiences produce lasting effects?

Multi-year observations and interviews assess whether changes are temporary or enduring. Many informants -- such as George, who reported healing from an untreatable brain tumor through prayer alone -- claimed they were still healed as many as eight years later. George and others had subsequently prayed for others who in turn reported healing, and this new cohort prayed for still others, sometimes traveling to other countries to do so. Such ripple effects of healing prayer largely account for the wildfire spread of global pentecostalism.

Bringing these four cameras into focus produces a more complete picture of how prayer affects health than using any single study method. Can science prove the healing power of prayer? Science cannot prove the existence or nonexistence of a suprahuman force or whether such an entity answers prayer. But it is an empirical question how prayer practices affect health. And we can -- and should -- use empirical methods to answer this question.

...one thing could be a decline of morals, or not having/few if any in the first place. no debate... just think about it, is all. Such as wearing 'jammies' out in public... fashion statement or no fashion statement who'd just follow along such an "out in the open" move? for lack of better words, I'm having trouble articulating that).

hasn't this last generation been exposed to every kind of open sex you can think of, including abuse?

Prayer always works when you make sure to add, "not my will...but Thy will be done".

Yes, you are soooo right.

Prayer means to see a fact or challenge without any complaining, blaming, feeling guilty. When you bear the friction between 'what is' and 'what you think should be' without any explanation, theory-you get a touch of the Original energy. Healing happens.

1. From a Biblical standard, among other factors, the kind of believers doing the praying is critical, and enlisting born again group with other groups would be inconclusive, as God need not affirm false religion by seemingly answering their prayers. Nor is it possible to ensure that the control group which are not being prayed for by group in the study were not being prayed for by many outside the groups.

2. In a typical study, a control group are asked to pray for a specific thing for a control group, with success being determined if that request was answered. However, Scriptural prayer presumes a communion with God in which He inspires who and what to pray for, and we can be impressed to pray for a different outcome. While the Christian is to pray, in Scripture and in my experience, the prayers that i have found most efficacious are those which He inspires.

3. Groups in a typical study were asked to pray for a large group of souls and compared with a another group, but they were not allowed to visit or see them (and were only given a first name and last name initial.) However, while this can take place as per the above, yet this degree of restriction is overall contrary to community, which normally prayer is not divorced from, and usually fosters, versus perfunctory or rote prayer. (Only in one case i think was anyone physically healed by Jesus Himself without a personal encounter)

What claptrap.

1. You imply your god will only answer the prayers of people who worship him properly. What an egomaniac he must be.
2. You imply that your god will only answer your prayers if you pray for something he told you to pray for. In other words, he'll only help you if he feels like it and you beg him .
3. You imply that your god only listens if you get a bunch of people together and even then, he will act only if the benificiaries are part of the group. So prayer itself is useless unless the beneficiary is one of the proper worshippers.

Three great rreasons why a study that shows prayer to be ineffective (and there have been many already), doesn't count.

1. Covenanted community is necessary in basic creed. But then again some people think anybody should be able allowed to fight in the U.S. Army regardless of where their national loyalties lie, and some people want moral and spiritual laxity, but God has rules which are to our benefit.

2. Your interpretation misunderstands what is taught. Mere feelings are not determinative of God's will as God operates according to love, righteousness and wisdom, doing what he knows is ultimately best, even if you think your idea of how to build the universe might be better.

As for begging, rather than being an egomaniac as elitist atheistic thinking imagines, God is constantly giving, and would save himself a lot of grief and trouble if we were all robots.

Worshiping Him is not something He needs, as God needs nothing, (Acts 17:25) nor does a parent necessarily require attention or obedience because they need ego fulfillment. But In contrast to created things which men will worship otherwise, as God alone is infinite, omnipotent perfect and eternal, and it is right and best for man that He and not finite creative things be our God. And many atheists think it is best for men to listen to them and their objectively baseless reasoning.

As for heart requirements of humility, love and faith, these are because God values character, that we be like Christ, God manifest in the flesh.

1) OUR Father, will take any prayer and He'll heal you with no strings attached what-so-ever.

2) Our God answers all prayers... we need only pay attention to the real signs and clues He'll send.

3) Our God will take prayer anytime, anywhere. You can go to Him for anything. I said, anything.

My dear friend, someone gave you poor information. I "almost" had breast cancer. It took 5 days of not ceasing in gentle morning prayer. On the 5th day I got this feeling to "stop". My doctors are amazed. I have the X-rays to prove it.

This isn't a carnival act. Try prayer before you go to sleep; saying a simple prayer or anything you like; talk to Him. .... then wait. for a real answer...

Peace be with you.

3. This relates to number one but two groups. The groups I was talking about was not only the prayer group but also the group that they were called to pray for, in which I advocated some sort of community between the two, as prayers is to have a larger holistic purpose.

As for prayer not being effective, that is what is pompous, as anyone who has lived in such a way of faith that prayers had to be answered can tell you, in which the answers cumulatively overall deny reasonable naturalistic explanations. I can give you some examples if you want.

I'd be very interested in seeing your examples of the efficacy of prayer in which none of these factors come into play:
1) coincedence (I prayed that I'd win the lottery, and I won the lottery)
2) self-fulfillment (we all prayed for pizza and then Dave ordered a pizza)
3) statistical significance (every time I take a plane I pray it won't crash, and I've never been in a plane crash; or less selfishly, I prayed for 100 people to recover from cancer, and 51 did - if 50 is the normal survival rate)
4) false attribution to prayer (my house was on fire, so I prayed for it to be put out, and along came the fire department and put out the fire).

There may be other factors; I just came up with those off the top of my head.

Fire away!
09:58 PM on 03/15/2012
OK, but as regards #1, there is little that a determined atheist cannot attribute to coincidence, even if it cumulatively goes against the law of averages so much as to attribute powers of deity to coincidence.

Let me begin by saying that in 1986 I left a good job and steady pay and home (I was single, and paid rent) to serve the Lord full-time, without pay. This was due to a call I strongly felt the Lord placed upon my life. I simply prayed that if this was God's will he would take care of what I needed to do His work.

In all the years since have I never received a salary, nor government support, nor lived by engaging in solicitation of the public or of churches, but as needed God has and does bring me to encounter a few isolated ( typically) individuals or couples from time to time who offer to help, though i rarely asked. Yet i lived from year to year with no certain income, but seeing God provide. He is simply merciful and faithful.

I say this to say that we have honestly had to see God literally work, and often have in profound ways, as well as faced challenges in which I my faith was tried, which is also entirely consistent with his word — as is suffering correction when I tried (and I do sometimes) to take an easier road than the way of the cross.

Here's a test for prayer. Stand in the middle of a Kansas wheat field in the middle of one hundred consecutive, steady-state, squall-line thunderstorms. Hold onto a 50' steel pole sticking straight up into the sky.

Then pray for the lightening to strike someone else who you know really deserves it. You can optionally also throw in a prayer that the lightening not strike near you.

Within 100 tries at this, your prayer is bound to be answered, one way or another.

Sez you. Tell that to the baptists. And while you're making up all these little rules, why not confer with your god to have them widely distributed, quickly, as in years ago.

But I'll work with you on this. Stand in the wheat field in the steady thunderstorms. By the flagpole. Then pray all night for a cure for cancer. Repeat this process as long as it takes to see some sort of tangible result, one way or another.

If God sent someone out on a mission, it's my beliefs that your silly quest to seek God most assuredly will work. it's "May God's will be done, but He's got you covered just the same, maybe under the heading of... God protects children/fools. common sense

I'm a servant of God. but I'm not going anywhere unless I hear from HIM. first..

Of course proximal intercessory prayer works sometimes, it can be the placebo effect. That is why other researchers use the double-blind study method. The placebo effect can be powerful.

Praying for something, asking God for something, accepting God says yes to some and no to others seems to be based on mythology; God, on the throne, sitting in judgement. What if we let those old ideas go? What if we claim God as the "One" the Source of all, but not a deity; divine and apart of all. That being said, do not "ask" in a prayer, command it. We do have that (power) within each of us.

If God knows and controls everything, and therefore allows you to become ill, he certainly already knows the outcome of the sickness. If this is the case, then how is prayer even worth the time? Prayer for the recovery of the sick is basically asking God to change his mind, which he cannot do because he already knows the outcome, but he is all powerful so he can do anything, so he should be able to change his mind, but wouldn't he have known that to begin with? I'm confused...

Ten years ago my sister-in-law was laying in an ICU after a complicated pancreas surgery. She was critical and if she survived the next few days, she was scheduled to be hospitalized for two weeks. I walked into the tiny, ice-cold room and all I could think to do was lay my hand on her forehead. I started to talk to God asking Him to heal her. My hand got so hot it was visibly red. It just about freaked me out, nothing like that had ever happened before. But to her doctors absolute amazement, she was doing so well she went home 2 days later. Praying for a stranger isn't the same as praying for someone known to you. They say, in fact, that for the most effective prayer you should visualize the person you are praying for, say their name, ask for specific things. People can scoff all they want but prayer is effective. I should know because with advanced cancer, I'm still here after 5 years and much has to do with my friends praying for me.
01:46 PM on 03/10/2012
Yes indeed I do belive in prayer and in the laying on of hands. Even your thoghts are full of energy so visualizing and seing the healing rays of light coming through you as you pray and lay your hands on your love ones can be very effective. I just finished reading a book called "Born To Heal" by Ruth Montgomery about this child that develped amazing healing abilities that evolved into being able to heal people even over the phone and also re-mote view to get answers in the process to heal people. You say that you are a cancer survivor. Praise be to our LORD! Be sure to read bout a blog post that I did called "Things To Do To Stop Fedding Cancer here. http://wp.me/p1Crrw-2k - Most people unawares are consuming and using TOXIC products that will continue feeding cancer. Hope that this helps. I pray that the LORD will continue to bless you beyound measure.

The most definitive, double blind studies - sponsored by the pro-religion Templeton Foundation showed no positive effects from prayer. In fact, the control group of cardiac patients that knew they were being "prayed for" actually did slightly worse than those who received no prayers or we're not told about being prayed for. Ask yourself this, if you were to accidently cut off a finger with a power tool, would you pray for it to be reattached, or would you bandage the wound tightly, throw the digit on ice and head to the nearest emergency treatment center, promptly?

I am a 36yr old man who is deaf, since the age of 1. I currently wear superpower hearing aids to help me hear some speech. However, for the last 6 years, I have been praying for my ears to open. If not every day, every other day, I'd remind God and ask Him for healing and thank Him for it. I've fasted, shared my belief and faith that He will heal me with many people. With eagerness, I've acted on my faith and created an evangelical testimony website (which will be made live after my healing). However, at times though, I wonder why I'm still deaf? Matter of fact, my hearing has been getting worse. I know healing comes from God, but is there something I am failing to do? Re P.I.P, does someone else need to pray for me?

Yes. That's the beauty of prayer. If God does not heal you, it means you've done something wrong and it's your fault.
