He writes: “Above the Apostle said that we must always remain dead to sin. Now he reasons about resurrection to new life according to God, which we must always possess. If through baptism we died with Christ, then we believe that we shall always have present in us the resurrection which consists in new life. For Christ also, having risen from the dead, lives always and will die no more.”
Agreeing with this interpretation, we shall take the word “we believe” as “let us believe,” seeing in it an exhortation, counsel, and instruction (see Oecumenius). In the words “that we shall also live with Him,” we shall see either an obligation or an encouragement.
In the words of blessed Theophylact, the first is contained, that we must always possess new life. But the second also appears, that we believe we shall always have resurrection present in us.
If we have died with Christ, having received hatred of sin and love of righteousness, then let us believe, and let us hold the conviction, that henceforth we must live with Him who is risen. We must walk in newness of life, in brightness and purity corresponding to the brightness of the risen Lord.
Thus the obligation is expressed. The encouragement may be expressed thus: if we have died with Christ, let us believe that we shall be able hereafter to live with Him. We shall be able to live so as to please Him, walking blamelessly in His holy will.
We shall live so because we are united with Him, living by His power, which pours from Him into us.
That such a thought may be understood here is justified by the form of expression: “and we believe that we shall also live with Him.” Let us nourish the hope that, having shared in His death, we shall not be strangers to the power of His resurrection.
Nor shall we be strangers to the firmness and constancy of the spiritual life renewed by Him in us, because of our unceasing communion with Him, who is risen and dies no more.
The occasion for such encouragement may be seen in the preceding exhortation: to be always dead to sin and not serve it, after the old man in us was crucified in baptism by the power of Christ’s death.
Having recognized his obligation to this, everyone may be shaken by perplexity: How can I do this, when I feel the assaults of sin and when the whole body of the passions has not yet been destroyed in me?
Anticipating this, the Apostle speaks as if to say: Do not be troubled. You have in yourself the power of the risen Lord, and by it you will conquer everything. You will not yield to sin or die by it, but will remain alive, always walking with the Lord and by the power of the Lord in newness of life.
Strengthen this hope in yourself by the fact that Christ, having risen, no longer dies, and death can no longer have dominion over Him. As He cannot die, so you, united with Him, will not die by sin. As death cannot have dominion over Him, so sin will not have dominion over you, because Christ is with you.
