" When Peter says, “Baptism . . . now saves you,” he’s saying something similar to what we affirm when we say, “The gospel saves you.” The gospel is God’s promise. It’s the promise that the death and resurrection of Jesus have dealt with the problem of sin and judgment—if we put our faith in Jesus. Baptism is that promise in physical form. "
