But now we believe. Therefore faith has already been reckoned to us as righteousness, and we are justified. Glory to the boundless mercy of God. We are justified! For if we are justified, then we have peace with God through the Lord Jesus. The dread decree, “the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men,” can no longer fall upon us. The wrath of God, which worthily and justly threatened us, has passed by. We are in God’s mercy, reconciled with Him through the Lord.
This is the first good that faith brings into the heart. The sinner, having come to consciousness of his sinfulness before God, sees the sword of righteousness over his head, ready to strike him. Saint Paul began his discourse on the wondrous manner of salvation in the Lord by pointing to this. He said: behold, the wrath of God is ready to strike sinners. Neither those outside the law nor those under the law will escape it.
But behold, the merciful God has arranged the manner of salvation through the death of His Son, all-powerful and all-embracing. Whoever hides beneath His shelter is hidden from the wrath of God. His sins are forgiven, and he is received into God’s peace. We who believe in the Lord who died and rose have been counted worthy of this good. Glory to Thee, O Lord! We have peace with God.
The consideration of justification is finished, as though a victory has been won. Now the Apostle surveys what this victory has given. In doing this, on the one hand, he invites those who have not yet believed under the shelter of faith. He says, as it were: let us cast off stubbornness, and let all hasten to reconciliation with God through faith in the Lord and Savior. On the other hand, he persuades those who have believed to remain in the peace that has been given. He says, as it were: let us be zealous to remain in this peace, living in the spirit of faith.
Our interpreters all emphasize chiefly the latter point. But Chrysostom, and Oecumenius after him, lightly indicate the former as well. These are the words of blessed Theodoret: “Having shown the power of faith and disclosed the gifts of grace, the Apostle turns his discourse to exhortation, persuading them to care for active virtue. Although faith has granted us remission of sins and through the laver of regeneration has made us pure and righteous, still you must preserve the peace established with God. For the Only-begotten, by becoming man, reconciled you, who were in enmity, with God. Sin produced this hostility, and righteousness preserves the peace that has been established.”
These are the words of Chrysostom: “What does ‘we have peace’ mean? Some explain that we must not rise up against grace by stubbornly supporting the law. But it seems to me that the Apostle gives us instruction about how we must conduct ourselves. Since above, after many discussions about faith and about justification by works, he preferred faith, someone might take such teaching as an occasion for carelessness. Therefore he says, ‘let us have peace,’ that is, let us no longer sin or return to our former state, for this would mean warring against God.
You ask: how is it possible to reach the point of sinning no more? I ask: how was it possible to be set free and redeemed from sins? If we, being so guilty, have been freed from all sins by Christ, then with His help it is much easier for us to remain in the state into which He has brought us. It is one thing to receive peace that did not exist, and another to preserve what has already been given. Acquiring is always harder than preserving. Meanwhile the harder thing has already been made easy and brought to completion. Therefore we shall succeed without difficulty in the easier thing, if we cleave to Him who accomplished the harder for us.
I think also that the Apostle leads us here to this thought: not only is success in preserving this peace easy, but the very act of preserving it is necessary on our part, by moral necessity, as an obligation. For if Christ reconciled us when we were enemies, then it is necessary on our part to remain reconciled and thereby repay His benefactions. Otherwise it would turn out that He reconciled to the Father those who are hardhearted and ungrateful.”
