The Bible tells us to prayer one for another.
The effectual fervent prayer of a righteous man availeth much. James 5:16b (KJV)
28 Come unto me, all ye that labour and are heavy laden, and I will give you rest.
29 Take my yoke upon you, and learn of me; for I am meek and lowly in heart: and ye shall find rest unto your souls. Matthew 11:28-29 (KJV)
