3:31 Do we then overthrow the law by this faith. See “Antinomianism” at 1 John 3:7. Paul is rejecting the law as the way of salvation. But since the law as moral demand was not given to sinners in order to justify them (vv. 19, 20), the principle of salvation by grace through faith cannot be a contradiction of the law. As he later demonstrates, the gospel upholds and furthers the law’s ultimate goal (8:3, 4; 13:8–10).
