James 5:13-20 - The Effective Prayer Of Faith
13 Is any one of you suffering ill-treatment? He should keep on praying. Is anyone in a happy mood? He should keep on singing praise to God. 14 Is anyone sick among you? He should call in the elders of the church, and they should pray over him, and anoint him with oil in the name of the Lord, 15 and the prayer that is offered in faith will save the sick man; the Lord will raise him to health, and if he has committed sins, he will be forgiven. 16 So practice confessing your sins to one another, and praying for one another, that you may be cured. An upright man's prayer, when it keeps at work, is very powerful. 17 Elijah was a man with feelings just like ours, and yet he earnestly prayed for it not to rain, and it did not rain on the land for three years and six months. 18 Then again he prayed, and the heavens yielded rain and the earth produced its crops.
19 My brothers, if any one of you has wandered away from the truth, and someone brings him back, 20 you may be sure that whoever brings a sinner back from his evil ways will save the man's soul from death, and cover up a multitude of sins.
