He was a new man. He didn't do that any more. So here's how it happens. We apply this to Baptism. But the new birth is more than baptism.
Baptism is the outward sign of a new inward experience.
Baptism is the public confirmation that an inward change has already taken place. Baptism does not create the new birth. Baptism is like a wedding ceremony. The wedding ceremony does not create Love. Weddings do not initiate love between a man and a woman.
