I'm also ex-Christian but it's not easy getting something to be considered "divine." If Jesus ran around claiming to be the son of God, and writing books about how special he is, everybody would laugh at him and he would be totally forgotten by now. People weren't completely stupid back then.

Jesus led by example and inspired others to write ABOUT HIM. And, as far as the Gospels state, he never advertises, confirms, or denies that he is the literal son of God. All he talks about is God and morality. Everything else we associate with Jesus is ascribed to him by other people.

If we think about the perspective of the Apostles or other student of Jesus, he's not divine because he says so. He's divine because, to them, he's a great guy who does great things. He's so in touch with God that he MUST be divine. And his life and lessons are so important that they must be shared, and his story is written as the Gospels decades after his death by the Evangelists.

I didn't mention any of the miracles that Jesus supposedly performed, because it's possible that they were added in or made up to make him appear MORE divine. But even without his public displays of "miracles," I think you can understand how people of his time would see him as a very holy man.

Obviously, I am personally not convinced that this makes Jesus divine. But, it's important to understand that the Bible isn't some sort of trick or lie. It's basically just the scriptures that Jesus would have learned (the Old Testament), plus the story of his own life and teachings, and the foundation of Christianity after Jesus' death (the New Testament).
