"Is anyone among you suffering? He should pray. Is anyone in good spirits? He should sing praise, Is anyone among you sick? He should summon the presbyters of the church, and they should pray over him and anoint with oil in the name of the Lord, and the prayer of faith will save the sick parson, and the Lord will raise him up. If he has committed any sins, he will be forgiven.
Therefore, confess your sins to one another and pray for one another, that you may be healed. The fervent prayer of a righteous person is very powerful. Elijah was a human being like us: yet he prayed earnestly that it might not rain, and for three years and six months it did not rain upon the land. Then he prayed again, and the sky gave rain and the earth produced it's fruit.
My brothers, if anyone among you should stray from the truth and someone bring him back, he should know that whoever brings back a sinner from the error of his way will save his soul from death and will cover a multitude of sins.---James 5:13-20"
