Paul's inspired writing gives the believer much assurance that nothing can separate us from the love of God. Many are persuaded, as he was, regarding the sovereignty of our Lord. His inspired writings in this particular passage reveal the doctrines of predestination, justification, redemption, and salvation.
In Romans 8:30-39, Paul writes:
"Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.What shall we then say to these things? If God be for us, who can be against us? He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things? Who shall lay any thing to the charge of God’s elect? It is God that justifieth. Who is he that condemneth?It is Christ that died, yea rather, that is risen again, who is even at the right hand of God, who also maketh intercession for us. Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?As it is written, For thy sake we are killed all the day long; we are accounted as sheep for the slaughter. Nay, in all these things we are more than conquerors through him that loved us.For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord."
One of the best commentaries on this passage was written by Matthew Henry:
What shall we then say to these things? What use shall we make of all that has been said? He speaks as one amazed and swallowed up with the contemplation and admiration of it, wondering at the height and depth, and length and breadth, of the love of Christ, which passeth knowledge. The more we know of other things the less we wonder at them; but the further we are led into an acquaintance with gospel mysteries the more we are affected with the admiration of them.
If Paul was at a loss what to say to these things, no marvel if we be. And what does he say? Why, if ever Paul rode in a triumphant chariot on this side of heaven, here it was: with such a holy height and bravery of spirit, with such a fluency and copiousness of expression, does he here comfort himself and all the people of God, upon the consideration of these privileges. In general, he here makes a challenge, throws down the gauntlet, as it were, dares all the enemies of the saints to do their worst: If God be for us, who can be against us? The ground of the challenge is God's being for us; in this he sums up all our privileges.
This includes all, that God is for us; not only reconciled to us, and so not against us, but in covenant with us, and so engaged for us—all his attributes for us, his promises for us. All that he is, and has, and does, is for his people. He performs all things for them. He is for them, even when he seems to act against them. And, if so, who can be against us, so as to prevail against us, so as to hinder our happiness? Be they ever so great and strong, ever so many, ever so might, ever so malicious, what can they do? While God is for us, and we keep in his love, we may with a holy boldness defy all the powers of darkness.
Let Satan do his worst, he is chained; let the world do its worst, it is conquered: principalities and powers are spoiled and disarmed, and triumphed over, in the cross of Christ. Who then dares fight against us, while God himself is fighting for us? And this we say to these things, this is the inference we draw from these premises.
It is Christ that died...It is by virtue of our interest in Christ, our relation to him, and our union with him, that we are thus secured. His death: It is Christ that died. By the merit of his death he paid our debt; and the surety's payment is a good plea to an action of debt. It is Christ, an able all-sufficient Saviour.
His resurrection: Yea, rather, that has risen again. This is a much greater encouragement, for it is a convincing evidence that divine justice was satisfied by the merit of his death. His resurrection was his acquittance, it was a legal discharge. Therefore the apostle mentions it with a yea, rather. If he had died, and not risen again, we had been where we were.
His sitting at the right hand of God: He is even at the right hand of God—a further evidence that he has done his work, and a mighty encouragement to us in reference to all accusations, that we have a friend, such a friend, in court. At the right hand of God, which denotes that he is ready there—always at hand; and that he is ruling there—all power is given to him.
What shall we say to these things? Is this the manner of men, O Lord God? What room is left for doubting and disquietment? Why art thou cast down, O my soul? Some understand the accusation and condemnation here spoken of ~ that which the suffering saints met with from men. The primitive Christians had many crimes laid to their charge—heresy, sedition, rebellion, and what not? For these the ruling powers condemned them: "But no matter for that" (says the apostle); "while we stand right at God's bar it is of no great moment how we stand at men's. To all the hard censures, the malicious calumnies, and the unjust and unrighteous sentences of men, we may with comfort oppose our justification before God through Christ Jesus as that which doth abundantly countervail," ( 1 Cor 4:3-4 )
We have good assurance of our preservation and continuance in this blessed state to the end ( Rom 8:35 ). The fears of the saints lest they should lose their hold of Christ are often very discouraging and disquieting, and create them a great deal of disturbance; but here is that which may silence their fears, and still such storms, that nothing can separate them.
