9 For this is the witness, or testimony, of God The particle ὅτι does not mean here the cause, but is to be taken as explanatory; for the Apostle, after having reminded us that God deserves to be believed much more than men, now adds, that we can have no faith in God, except by believing in Christ, because God sets him alone before us and makes us to stand in him. He hence infers that we believe safely and with tranquil minds in Christ, because God by his authority warrants our faith. He does not say that God speaks outwardly, but that every one of the godly feels within that God is the author of his faith. It hence appears how different from faith is a fading opinion dependent on something else.

10. He that believeth not As the faithful possess this benefit, that they know themselves to be beyond the danger of erring, because they have God as their foundation; so he makes the ungodly to be guilty of extreme blasphemy, because they charge God with falsehood. Doubtless nothing is more valued by God than his own truth, therefore no wrong more atrocious can be done to him, than to rob him of this honor. Then in order to induce us to believe, he takes an argument from the opposite side; for if to make God a liar be a horrible and execrable impiety, because then what especially belongs to him is taken away, who would not dread to withhold faith from the gospel, in which God would have himself to be counted singularly true and faithful? This ought to be carefully observed.

Some wonder why God commends faith so much, why unbelief is so severely condemned. But the glory of God is implicated in this; for since he designed to shew a special instance of his truth in the gospel, all they who reject Christ there offered to them, leave nothing to him. Therefore, though we may grant that a man in other parts of his life is like an angel, yet his sanctity is diabolical as long as he rejects Christ. Thus we see some under the Papacy vastly pleased with the mere mask of sanctity, while they still most obstinately resist the gospel. Let us then understand, that it is the beginning of true religion, obediently to embrace this doctrine, which he has so strongly confirmed by his testimony.

11 That God hath given us eternal life Having now set forth the benefit, he invites us to believe. It is, indeed, a reverence due to God, immediately to receive, as beyond controversy, whatever he declares to us. But since he freely offers life to us, our ingratitude will be intolerable, except with prompt faith we receive a doctrine so sweet and so lovely. And, doubtless, the words of the Apostle are intended to shew, that we ought, not only reverently to obey the gospel, lest we should affront God; but, that we ought to love it, because it brings to us eternal life. We hence also learn what is especially to be sought in the gospel, even the free gift of salvation; for that God there exhorts us to repentance and fear, ought not to be separated from the grace of Christ.

But the Apostle, that he might keep us together in Christ, again repeats that life is found in him; as though he had said, that no other way of obtaining life has been appointed for us by God the Father. And the Apostle, indeed, briefly includes here three things: that we are all given up to death until God in his gratuitous favor restores us to life; for he plainly declares that life is a gift from God: and hence also it follows that we are destitute of it, and that it cannot be acquired by merits; secondly, he teaches us that this life is conferred on us by the gospel, because there the goodness and the paternal love of God is made known to us; lastly, he says that we cannot otherwise become partakers of this life than by believing in Christ.

12 He that hath not the Son This is a confirmation of the last sentence. It ought, indeed, to have been sufficient, that God made life to be in none but in Christ, that it might be sought in him; but lest any one should turn away to another, he excludes all from the hope of life who seek it not in Christ. We know what it is to have Christ, for he is possessed by faith. He then shews that all who are separated from the body of Christ are without life.

But this seems inconsistent with reason; for history shews that there have been great men, endued with heroic virtues, who yet were wholly unacquainted with Christ; and it seems unreasonable that men of so great eminence had no honor. To this I answer, that we are greatly mistaken if we think that whatever is eminent in our eyes is approved by God; for, as it is said in Luke,

“What is highly esteemed by men is an abomination with God.” (Luke 16:15)

For as the filthiness of the heart is hid from us, we are satisfied with the external appearance; but God sees that under this is concealed the foulest filth. It is, therefore, no wonder if specious virtues, flowing from an impure heart, and tending to no right end, have an ill odor to him. Besides, whence comes purity, whence a genuine regard for religion, except from the Spirit of Christ? There is, then, nothing worthy of praise except in Christ.

There is, further, another reason which removes every doubt; for the righteousness of men is in the remission of sins. If you take away this, the sure curse of God and eternal death awaits all. Christ alone is he who reconciles the Father to us, as he has once for all pacified him by the sacrifice of the cross. It hence follows, that God is propitious to none but in Christ, nor is there righteousness but in him.

Were any one to object and say, that Cornelius, as mentioned by Luke, (Acts 10:2,) was accepted of God before he was called to the faith of the gospel: to this I answer shortly, that God sometimes so deals with us, that the seed of faith appears immediately on the first day. Cornelius had no clear and distinct knowledge of Christ; but as he had some perception of God’s mercy, he must at the same time understand something of a Mediator. But as God acts in ways hidden and wonderful, let us disregard those speculations which profit nothing, and hold only to that plain way of salvation, which he has made known to us.
