James 5:14-18

Is any among you sick? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord: and the prayer of faith shall save him that is sick, and the Lord shall raise him up; and if he have committed sins, it shall be forgiven him. Confess 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. Elijah 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. And he prayed again; and the heaven gave rain, and the earth brought forth her fruit.
