Therefore, confess your sins to one another and pray for one another, that you may be healed. The effective prayer of a righteous person has great power. Elijah was a man with a nature like ours, and he prayed fervently that it might not rain, and for three years and six months it did not rain on the earth. Then he prayed again, and heaven gave rain, and the earth bore its fruit.
— James 5:16-18 (alt. reading v. 16)
