When people came to Jesus and wanted to know more about him, he did not preach them a sermon. He did not have classes and give lectures. He did not argue or write books. He simply said, "Come and see." He invited them to follow him into a completely new world, the world that God always intended. He called it the kingdom of God.
However, for centuries his followers (who think they know more than he does) have preached and argued and lectured and taught people into being Christians. None of that seems to work much anymore. We are living in a world where those old certainties have died. Good riddance. Perhaps our world is ready again for another approach. The way of Jesus. The way of "Come and follow."
