Bart Ehrman doesn’t believe that the Bible is the Word of God.
He did until he studied the Bible and found it was not the literal word of God he had been taught and once believed. What really ended his belief was the question of evil. Appropriate to the thread.
I understand his path. On the other hand, he is just one man. There are millions that have studied the bible and that studying has reinforced their faith, like me. I believe there is evil in the world, but God is not the evil one. The evil one is Satan, Jesus said so.
