What Dies in the Baptism Is the Dominion of Sin?

Paul: The baptism is not an outward sign of an inward change. What dies in the baptism is sin's dominion over you. Re sin. Sin no longer is your lord. Jesus is your lord, that's what's going on. And so he says in verse five, for if we have been united with him in a death like his, we shall certainly be united with him in a resurrection like his.
