Genesis 6:13

13.And God said unto Noah. Here Moses begins to relate how Noah would be preserved. And first, he says, that the counsel of God respecting the destruction of the world was revealed to him. Secondly, that the command to build the ark was given. Thirdly, that safety was promised him, if, in obedience to God, he would take refuge in the ark. These chief points are to be distinctly noted; even as the Apostle, when he proclaims the faith of Noah, joins fear and obedience with confidence, (Hebrews 11:7.) And it is certain that Noah was admonished of the dreadful vengeance which was approaching; not only in order that he might be confirmed in his holy purpose, but that, being constrained by fear, he might the more ardently seek for the favor offered to him. We know that the impunity of the wicked is sometimes the occasion of alluring even the good to sin: the denunciation, therefore, of future punishment ought to be effectual in restraining the mind of a holy man; lest, by gradual declension, he should at length relax to the same lasciviousness. Yet God had special reference to the other point; namely, that by keeping continually in view the terrible destruction of the world, Noah might be more and more excited to fear and solicitude. For it was necessary, that in utter despair of help from any other quarter, he should seek his safety, by faith, in the ark. For so long as life was promised to him on earth, never would he have been so intent as he ought, in the building of the ark; but, being alarmed by the judgment of God, he earnestly embraces the promise of life given unto him. He no longer relies upon the natural causes or means of life; but rests exclusively on the covenant of God, by which he was to be miraculously preserved. No labor is now troublesome or difficult to him; nor is he broken down by long fatigue. For the spur of God’s anger pierces him too sharply to allow him to sleep in carnal delights, or to faint under temptations, or to be delayed in his course by vain hope: he rather stirs himself up, both to flee from sin, and to seek a remedy. And the Apostle teaches, that it was not the least part of his faith, that through the fear of those things which were not seen he prepared an ark. When faith is treated of simply, mercy and the gratuitous promise come into the account; but when we wish to express all its parts, and to canvass its entire force and nature, it is necessary that fear also should be joined with it. And, truly no one will ever seriously resort to the mercy of God, but he who, having been touched with the threatening of God, shall dread that judgment of eternal death which they denounce, shall abhor himself on account of his own sins, shall not carelessly indulge his vices, nor slumber in his pollution; but shall anxiously sigh for the remedy of his evils. This was, truly, a peculiar privilege of grace, that God warned Noah of the future deluge. Indeed, he frequently commands his threatening to be proposed to the elect, and reprobate, in common; that by inviting both to repentance, he may humble the former, and render the latter inexcusable. But while the greater part of mankind, with deaf ears, reject whatever is spoken, he especially turns his discourse to his own people, who are still curable, that by the fear of his judgment he may train them to piety. The condition of the wicked might at that time seem desirable, in comparison with the anxiety of holy Noah. They were securely flattering themselves in their own delights; for we know what Christ declares concerning the luxury of that period, (Luke 17:26.) Meanwhile, the holy man, as if the world were every moment going to ruin, groaned anxiously and sorrowfully. But if we consider the end; God granted an inestimable benefit to his servant, in denouncing to him a danger, of which he must beware.

The earth is filled with violence through them. (274) God intimates that men were to be taken away, in order that the earth, which had been polluted by the presence of beings so wicked, might be purified. Moreover, in speaking only of the iniquity and violence, of the frauds and rapines, of which they were guilty towards each other; he does it, not as if he were intending to remit his own claims upon them, but because this was a more gross and palpable demonstration of their wickedness.
