"Is any of you in trouble? He should pray. Is anyone happy? Let him sing songs of praise. Is anyone sick? He should call the elders of the church to pray over him and anonint him with oil in the name of the Lord.
And the prayer offered in faith will make the sick person well; The Lord will raise him up. If he has sinned, he will be forgiven.
Therefore confess your sins to each other and pray for each other that you may be healed. The prayer of a righteous man is powerful and effective. Ephesians 5:13-16 (NIV)
