Who shall bring any charge against God's elect?

Calvin has this to say in his commentary on Romans 8:22.

The first and the chief consolation of the godly in adversities, is to be fully persuaded of the paternal kindness of God; for hence arises the certainty of their salvation, and that calm quietness of the soul through which it comes that adversities are sweetened, or at least the bitterness of sorrow mitigated. Hardly then a more suitable encouragement to patience could be adduced than this, a conviction that God is propitious to us; and hence Paul makes this confidence the main ground of that consolation, by which it behoves the faithful to be strengthened against all evils. And as the salvation of man is first assailed by accusation, and then subverted by condemnation, he in the first place averts the danger of accusation. There is indeed but one God, at whose tribunal we must stand; then there is no room for accusation when he justifies us. The antithetic clauses seem not indeed to be exactly arranged; for the two parts which ought rather to have been set in opposition to each other are these: “Who shall accuse? Christ is he who intercedes:” and then these two might have been connected, “Who shall condemn? God is he who justifies;” for God’s absolution answers to condemnation, and Christ’s intercession to accusation. But Paul has not without reason made another arrangement, as he was anxious to arm the children of God, as they say, from head to foot, with that confidence which banishes all anxieties and fears. He then more emphatically concludes, that the children of God are not subject to an accusation, because God justifies, than if he had said that Christ is our advocate; for he more fully expresses that the way to a trial is more completely closed up when the judge himself pronounces him wholly exempt from guilt, whom the accuser would bring in as deserving of punishment. There is also a similar reason for the second clause; for he shows that the faithful are very far from being involved in the danger of condemnation, since Christ by expiating their sins has anticipated the judgment of God, and by his intercession not only abolishes death, but also covers our sins in oblivion, so that they come not to an account.
