It's not only interesting, it's difficult to understand, and Old Testament contains a lot of stuff that makes you doubt. But if you look at it from a theological view, God's judgement does not disappear anywhere in New Testament. It's just diverted into one person: his own son, who he abandons to be crucified, even though he is innocent.
Christianity is really a horrifying religion. The core of it is disgusting and offensive.
But it doesn't end there.
The stories in the Bible are kind of comforting, in a way. It's basically a chain of generations after generations fucking everything up and doing every horrible thing mankind does. Yet through all that the message is that God is always the same and always waiting for his people to stop running away from him.
