James 5:16-18

16Therefore confess your sins to each other and pray for each other so that you may be healed. The prayer of a righteous man has great power to prevail. 17Elijah was a man just like us. He prayed earnestly that it would not rain, and it did not rain on the land for three and a half years. 18Again he prayed, and the heavens gave rain, and the earth yielded its crops.
