James 5:14-16

If any of you are sick, they should call for the elders of the church, and the elders should pray over them, anointing them with oil in the name of the Lord. Prayer that comes from faith will heal the sick, for the Lord will restore them to health. And if they have sinned, they will be forgiven. For this reason, confess your sins to each other and pray for each other so that you may be healed. The prayer of the righteous person is powerful in what it can achieve.
