She told me she could not sleep at night she had totally fallen apart after denying Jesus.. She is truly born again now. Also another one pretty much same story. She was muslim for about a month and during that time she became the most evil person. She was at war inside and she since Gave her life back also Praise God!!!! They got a taste of the darkness and realized it
