Reflecting on the fact that before his redemption his flesh was condemned to death by the Law of God, the Apostle Paul made the confession of faith that he was, by believing in Jesus Christ, dead to sin. Before we met the righteousness of God—that is, before we were born again—those of us who believe in Christ used to live under the dominion and curse of the Law. Thus, the Law would have had dominion over us had we not been redeemed of our sins by encountering Jesus Christ, who brought us the righteousness of God.
Paul spoke of spiritual matters that cannot easily be understood in the flesh—that is, those who are dead to sin are no longer under the dominion of sin, just as a woman whose husband has died is completely freed from her obligation to her husband. This passage may sound simple, but it is a spiritually crucial passage. It means that, whether they like it or not, those who have not met the righteousness of God are, as a matter of fact, fated to live under the curse of the Law. This is because they have not yet resolved the problem of their sins.
