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 so that you may be healed. The prayer of a righteous man is powerful and effective.

 Elijah 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.

James 5:15-17
