And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.

And not only so; but also we glory in God, through our Lord Jesus Christ, by whom we have now received reconciliation.

And not only that, but we are making our boast in God, through our Lord Jesus Christ, through whom now we have received the reconciliation.

And not only so, but we are also boasting in God, through our Lord Jesus Christ, through whom now we did receive the reconciliation;

And not only so, but we also exult in God through our Lord Jesus Christ, through whom we have now obtained that reconciliation.

And not only so, but we have joy in God through our Lord Jesus Christ, through whom we are now at peace with God.

And not only that, but we also glory in God through our Lord Jesus Christ, through whom we have now received reconciliation.

Non solum autem, sed etiam gloriamur in Deo per Dominum Iesum Christum, per quem nunc reconciliationem accepimus.

And not this only, etc. He now ascends into the highest strain of glorying; for when we glory that God is ours, whatever blessings can be imagined or wished, ensue and flow from this fountain; for God is not only the chief of all good things, but also possesses in himself the sum and substance of all blessings; and he becomes ours through Christ. We then attain this by faith, -- that nothing is wanting to us as to happiness. Nor is it in vain that he so often mentions reconciliation: it is, first, that we may be taught to fix our eyes on the death of Christ, whenever we speak of our salvation; and, secondly, that we may know that our trust must be fixed on nothing else, but on the expiation made for our sins.

And not only so - The apostle states another effect of justification.
We also joy in God - In Romans 5:2, he had said that we rejoice in tribulations, and in hope of the glory of God. But he here adds that we rejoice in God himself; in his existence; his attributes; his justice, holiness, mercy, truth, love. The Christian rejoices that God is such a being as he is; and glories that the universe is under his administration. The sinner is opposed to him; he finds no pleasure in him; he fears or hates him; and deems him unqualified for universal empire. But it is one characteristic of true piety, one evidence that we are truly reconciled to God, that we rejoice in him as he is; and find pleasure in the contemplation of his perfections as they are revealed in the Scriptures.
Through our Lord - By the mediation of our Lord Jesus, who has revealed the true character of God, and by whom we have been reconciled to him.
The atonement - Margin, or reconciliation. This is the only instance in which our translators have used the word "atonement" in the New Testament. The word frequently occurs in the Old, Exodus 29:33, Exodus 29:36-37; Exodus 30:10, Exodus 30:15-16, etc. As it is now used by us, it commonly means the ransom, or the sacrifice by means of which reconciliation is effected between God and man. But in this place it has a different sense. It means the reconciliation itself between God and man; not the means by which reconciliation is effected. It denotes not that. we have received a ransom, or an offering by which reconciliation might be effected; but that in fact we have become reconciled through him. This was the ancient meaning of the English word atonement - at one ment - being at one, or reconciled.
- He seeks to make atonement.
Between the duke of Glo'ster and your brothers.
- Shakespeare.
The Greek word which denotes the expiatory offering by which a reconciliation is effected, is different from the one here; see the note at Romans 3:25. The word used here καταλλαγὴ katallagē is never used to denote such an offering, but denotes the reconciliation itself.

We also joy (καυχωμενοι, we exult, or glory) in God, etc. - We now feel that God is reconciled to us, and we are reconciled to him: the enmity is removed from our souls; and He, for Christ's sake, through whom we have received the atonement, καταλλαγην, the reconciliation, has remitted the wrath, the punishment which we deserved: and now, through this reconciliation, we expect an eternal glory.
It was certainly improper to translate καταλλαγη here by atonement, instead of reconciliation; as καταλλασσω signifies to reconcile, and is so rendered by our translators in all the places where it occurs. It does not mean the atonement here, as we generally understand that word, viz. the sacrificial death of Christ; but rather the effect of that atonement, the removal of the enmity, and by this, the change of our condition and state; from κατα, intensive, and αλλασσω to change; the thorough change of our state from enmity to friendship. God is reconciled to us, and we are reconciled to him by the death of his Son; and thus there is a glorious change from enmity to friendship; and we can exult in God through our Lord Jesus Christ, by whom we have received this reconciliation. Though boasting is forbidden to a Jew, because his is a false confidence, yet boasting is enjoined to a Christian, to one reconciled to God; for, his boasting is only in that reconciliation, and the endless mercy by which it is procured. So he that glorieth (boasteth) must glory in the Lord.

(9) And not only [so], but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.
(9) He now passes over to the other part of justification, which consists in the free imputation of the obedience of Christ: so that to the remission of sins, there is added moreover and besides, the gift of Christ's righteousness imputed or put upon us by faith, which swallows up that unrighteousness which flowed from Adam into us, and all the fruits of it: so that in Christ we do not only cease to be unjust, but we begin also to be just.

And not only so, but we also joy in God,.... Something seems here to be understood, and which is to be supplied thus; not only we are saved by his life, and from wrath through him; not only are we reconciled to God by his Son, and Spirit; not only Christ has died for us while sinners and ungodly; not only do we glory in tribulations, and rejoice in hope of the glory of God: "but we also joy in God"; himself, as our covenant God and Father in Christ, as the God of all grace, peace, and salvation; in his perfections, as engaged on our side, and as glorified in our salvation; in the purposes of God, and his covenant transactions with his Son, as they are made known in the everlasting Gospel; in all his providential dispensations, which are mercy and truth; and in our being of him in Christ, and Christ's being made unto us wisdom, righteousness, sanctification, and redemption; in all the blessings of grace we receive from him, the glory of which is his due; and in his sight and presence, and in the enjoyment of him. The means by which saints come at this joying and glorying in God, is
through our Lord Jesus Christ; not the light of nature, nor the law of Moses, nor any works of righteousness done by men, nor through angels or saints, but Christ, and him only; for it is only in and through him that God is their covenant God and Father; by him only have they the agreeable view of his glorious perfections; in him only all his purposes and promises have their fulfilment; it is by his hands, and through his blood, that all the blessings of grace are conveyed to them; their access to God is only by him; and by him they give the praise and glory of every mercy to him. And the ground of this joy is the expiation of sin by Christ,
by whom we have now received the atonement; atonement is not made, but received by us; which denotes the application of the atoning blood and sacrifice of Christ to the conscience, the Spirit's witness of interest in it, and the office of faith, as a recipient of it: it is not faith, nor anything else of the creature's, that makes the atonement, only Christ; but faith receives it from him, and by him; which, as it is the ground of present joying in God, so it is the foundation of hope of future glory: the word "now" refers to the Gospel dispensation. The poor Jews are at the utmost loss about atonement: sometimes they tell (c) us it is by confession, repentance, and good works; sometimes by beneficence and hospitality (d); sometimes they say their captivity is their atonement (e); and, at other times, that death expiates all their sins (f). Blessed be God for the atoning sacrifice of Christ!

And not only so, but we also joy--rather, "glory."
in God through our Lord Jesus Christ, by--"through"
whom we have now received the atonement--rather, "the reconciliation" (Margin), as the same word is rendered in Romans 5:10 and in 2-Corinthians 5:18-19. (In fact, the earlier meaning of the English word "atonement" was "the reconciliation of two estranged parties") [TRENCH]. The foregoing effects of justification were all benefits to ourselves, calling for gratitude; this last may be termed a purely disinterested one. Our first feeling towards God, after we have found peace with Him, is that of clinging gratitude for so costly a salvation; but no sooner have we learned to cry, Abba, Father, under the sweet sense of reconciliation, than "gloriation" in Him takes the place of dread of Him, and now He appears to us "altogether lovely!"
On this section, Note, (1) How gloriously does the Gospel evince its divine origin by basing all acceptable obedience on "peace with God," laying the foundations of this peace in a righteous "justification" of the sinner "through our Lord Jesus Christ," and making this the entrance to a permanent standing in the divine favor, and a triumphant expectation of future glory! (Romans 5:1-2). Other peace, worthy of the name, there is none; and as those who are strangers to it rise not to the enjoyment of such high fellowship with God, so they have neither any taste for it nor desire after it. (2) As only believers possess the true secret of patience under trials, so, although "not joyous but grievous" in themselves (Hebrews 12:17), when trials divinely sent afford them the opportunity of evidencing their faith by the grace of patience under them, they should "count it all joy" (Romans 5:3-4; and see James 1:2-3). (3) "Hope," in the New Testament sense of the term, is not a lower degree of faith or assurance (as many now say, I hope for heaven, but am not sure of it); but invariably means "the confident expectation of future good." It presupposes faith; and what faith assures us will be ours, hope accordingly expects. In the nourishment of this hope, the soul's look outward to Christ for the ground of it, and inward upon ourselves for evidence of its reality, must act and react upon each other (Romans 5:2 and Romans 5:4 compared). (4) It is the proper office of the Holy Ghost to beget in the soul the full conviction and joyful consciousness of the love of God in Christ Jesus to sinners of mankind, and to ourselves in particular; and where this exists, it carries with it such an assurance of final salvation as cannot deceive (Romans 5:5). (5) The justification of sinful men is not in virtue of their amendment, but of "the blood of God's Son"; and while this is expressly affirmed in Romans 5:9, our reconciliation to God by the "death of His Son," affirmed in Romans 5:10, is but a variety of the same statement. In both, the blessing meant is the restoration of the sinner to a righteous standing in the sight of God; and in both, the meritorious ground of this, which is intended to be conveyed, is the expiatory sacrifice of God's Son. (6) Gratitude to God for redeeming love, if it could exist without delight in God Himself, would be a selfish and worthless feeling; but when the one rises into the other--the transporting sense of eternal "reconciliation" passing into "gloriation in God" Himself--then the lower is sanctified and sustained by the higher, and each feeling is perfective of the other (Romans 5:11).

And not only so, but we also glory - The whole sentence, Romans 5:3-11, may be taken together thus: We not only "rejoice in hope of the glory of God," but also in the midst of tribulations we glory in God himself through our Lord Jesus Christ, by whom we have now received the reconciliation.
