At this point, writers like Rauser and Olson forfeit any claim to be Christian. They don’t believe in the OT God. They find the OT God morally repugnant. And this is despite the fact that Jesus and the NT writers treat the OT God as the one true God. The God of the OT is the God of the NT.
Writers like Rauser and Olson don’t believe what Jesus believed. They don’t believe what other NT authors believed.
They come to Scripture with a preconception of what God, if there is a God, must be like. When they don’t find what they’re looking for in the Bible, when they encounter depictions that challenge their preconceptions, they revile and deny the offending depictions.
