If anyone doubts the power of prayer, please read this story by a mother who prayed unceasingly for her wayward son:
My prayers were unceasing now. Not a half an hour went by that I did not talk to God about my son and ask His Blessed Mother to keep praying for Donnie. He returned home at nineteen. If nothing else, at least he was home with us, I thought. Shortly thereafter, my husband was transferred to Virginia. Donnie came with us.
