Sam Cullum had grown up in a secure, happy, Christian home.
Yet when he was 15, after splitting up with his girlfriend, he began to self-harm, cutting himself with scissors.
"Why did I do it? In a strange sort of way, I guess the physical pain took away some of the emotions I was feeling - it made me forget about my problems."
Sam started to hang around with other young rebels in his home town of Coventry. The "Lady Godiva" statue was a well-known place for alienated "Goths, skaters and grebes" to hang out.
"I felt accepted there," says Sam, "because I wasn't the only one who self harmed."
It was around this time that Sam was invited to a Jesus Army event.
Sam had experienced God for himself at a Christian camp, years earlier so he decided to go along. He was unprepared for the power he encountered.
"I told them that I self-harmed and was prayed for. It blew my head off. Throughout the prayer, I was screaming, but at the end of it I felt so joyful.
"When I went to cut myself the next day I found I just couldn't. Something was physically stopping me. I was amazed. God had done something real."
With his parent's blessing, Sam started to come to the Jesus Army more and was baptised as a Christian. At his baptism someone said that he would "do battle with the devil".
