James 5:13-20 - The Effective Prayer Of Faith
13 Does any suffer among you? let him pray. Is any cheerful? let him play on the harp. 14 Is any sick among you let him call for the elders of the church; and let them pray over him, having anointed him with oil in the name of the Lord: 15 And the prayer of faith shall save him being sick, and the Lord will raise him up; and if he should have wrought sins, it shall be remitted to him. 16 Acknowledge your faults to one another, and pray for one another, that ye might be healed. The prayer of the just, being energetic, is very powerful. 17 Elias was a man having similar feelings with us, and in prayer he prayed for it not to rain: and it rained not upon the earth for three years and six months. 18 And again he prayed, and the heaven gave rain, and the earth shot forth her fruit.
19 Brethren, if any among you be led astray from the truth, and any should turn him back; 20 Let him know, that he having turned the sinful from the error of his way shall save a soul from death, and shall cover a multitude of sins.
