I think losing one's faith is dangerous. Just before my younger brother died he blamed his situation on his up bringing. My older brother is ill. He also feels some of his trouble started post 1975.
If I lost my faith in Christ I think I would suffer alot.
When I left the "truth" in alot of ways I wanted my wife to stay. One reason was I felt she could be leaving because of me. I wanted her to leave because she didn't accept it not because I didn't also it makes it more difficult for me to gauge my reasoning.
