As Christians, are we fully-redeemed saints of God, or are we still sinners? As believers in Christ, while we live in this earthly dominion, we are also a part of God’s heavenly dominion. In other words, we have one foot on earth and one foot in heaven. Our citizenship is simultaneously in both our heavenly and earthly nations.
Paul speaks of “dominion” in Romans 6:14-15,
“14 For sin will have no dominion over you, since you are not under law but under grace.
15 What then? Are we to sin because we are not under law but under grace? By no means!”
In v. 14, Paul seems to be implying a sense of authority rather than a sense of mastery or domination (The definition of dominion might include: jurisdiction; territory of a sovereign/government; sovereign control; supremacy; domination; authority; command; power; etc.).
If he was implying mastery, he would not have asked the rhetorical question in v. 15 Paul was warning Christians to refrain from taking advantage of God’s grace by intentionally committing sins we know are wrong. It implies that we as Christians have the potential to commit sins we already know are wrong. We may be redeemed but we are not free to sin whenever we want (6:12, 15).
Within the church, there is a debate whether we are still sinners. Some would say we are no longer sinners but redeemed saints of God, and have the potential of moral perfection. Others would say we are still sinners and cannot stop sinning even if we tried.
The body of Christ and our Christian leaders are far from moral perfection. It is only Christ who is totally righteous and it’s only through his sanctification that we are made righteous (Rom. 6:11, 4:24). I believe Luther was right about humanity’s sin and God’s grace. The doctor of theology, Martin Luther, said we are simultaneously both saint and sinner. He accepted both realities about man’s sin and redemption. Humanity’s sin is utterly depraved while we are still in a state of being redeemed. If we are in God’s dominion of grace, we can be assured that we have eternal life, and have been, and will be fully, set free from sin and death because God has promised this.
