Adam and Christ in Romans 5:12–21
Paul sets Adam and Christ side by side to show that one man's disobedience explains the universal problem of sin and death, and one man's obedience is God's greater answer. The gift does not merely mirror the trespass; it moves many trespasses to justification and transfers the rule of life from sin to grace.
Romans 6:1–4: Why Baptism Matters
Paul answers the idea that grace gives us room to keep sinning by pointing to baptism. Baptism matters because it marks a real union with Christ in his death and resurrection, a break with sin's rule and the start of a new life.
Romans 6:1–4: Baptism Into His Death
Paul refuses the idea that grace gives room to keep sinning, and he grounds his answer in baptism. Being baptized into Christ means sharing his death and burial, which points forward to walking in newness of life.
