James 5:16-20

16Confess therefore your sins one to another, and pray one for another, that ye may be healed. The supplication of a righteous man availeth much in its working. 17Elijah was a man of like passions with us, and he prayed fervently that it might not rain; and it rained not on the earth for three years and six months. 18And he prayed again; and the heaven gave rain, and the earth brought forth her fruit. 19My brethren, if any among you do err from the truth, and one convert him; 20let him know, that he which converteth a sinner from the error of his way shall save a soul from death, and shall cover a multitude of sins.
