Christian music singer Steven Curtis Chapman is still coping with the death of his adopted daughter, 5-year-old Maria, who was accidentally struck in the family's driveway by one of her brothers who was returning home in his truck in May 2008.

Chapman, who has been singing Christian music for more than 20 years, told CNN that he felt like he was in a black hole and faced with a God he had not known before. Everything he thought about God was different, he said, and he began to wrestle with his beliefs.
