James 5:14-16

14 Is any among you sick? Let him call for the elders of the assembly, and let them pray over him, anointing him with oil in the name of the Lord,  15 and the prayer of faith will heal him who is sick, and the Lord will raise him up. If he has committed sins, he will be forgiven.  16 Confess your offenses to one another, and pray one for another, that you may be healed. The effective, earnest prayer of a righteous man is powerfully effective.
