God sent Jesus to join the human experience, which means to make a lot of mistakes. Jesus didn't arrive here knowing how to walk. He had fingers and toes, confusion, sexual feelings, crazy human internal processes. He had the same prejudices as the rest of his tribe: he had to learn that the Canaanite woman was a person. He had to suffer the hardships and tedium and setbacks of being a regular person. If he hadn't the incarnation would mean nothing.
