And the LORD said, My spirit shall not always {d} strive with man, for that he also is flesh: yet his days shall be an {e} hundred and twenty years.

(d) Because man could not by won by God's leniency and patience by which he tried to win him, he would no longer withhold his vengeance.

(e) Which time span God gave man to repent before he would destroy the earth, 1Pe 3:20.

Wesley's Notes

6:3 My spirit shall not always strive with man - The spirit then strove by Noah's preaching, 1Pet 3:19, and by inward checks, but 'twas in vain with the most of men; therefore saith God, he shall not always strive, for that he also is flesh - Incurably corrupt and sensual, so that 'tis labour lost to strive with him. He also, that is, all, one as well as another; they are all sunk into the mire of flesh. Yet his days shall be an hundred and twenty years - So long will I defer the judgment they deserve, and give them space to prevent it by their repentance and reformation. Justice said, cut them down; but mercy interceded, Lord, let them alone this year also; and so far mercy prevailed, that a reprieve was obtained for six score years.

Jamieson-Fausset-Brown Bible Commentary

3. flesh-utterly, hopelessly debased.

And the Lord said, My spirit shall not always strive-Christ, as God, had by His Spirit inspiring Enoch, Noah, and perhaps other prophets (1Pe 3:20; 2Pe 2:5; Jude 14), preached repentance to the antediluvians; but they were incorrigible.

yet his days shall be an hundred and twenty years-It is probable that the corruption of the world, which had now reached its height, had been long and gradually increasing, and this idea receives support from the long respite granted.

Matthew Henry's Concise Commentary

6:1-7 The most remarkable thing concerning the old world, is the destroying of it by the deluge, or flood. We are told of the abounding iniquity of that wicked world: God's just wrath, and his holy resolution to punish it. In all ages there has been a peculiar curse of God upon marriages between professors of true religion and its avowed enemies. The evil example of the ungodly party corrupts or greatly hurts the other. Family religion is put an end to, and the children are trained up according to the worldly maxims of that parent who is without the fear of God. If we profess to be the sons and daughters of the Lord Almighty, we must not marry without his consent. He will never give his blessing, if we prefer beauty, wit, wealth, or worldly honours, to faith and holiness. The Spirit of God strove with men, by sending Enoch, Noah, and perhaps others, to preach to them; by waiting to be gracious, notwithstanding their rebellions; and by exciting alarm and convictions in their consciences. But the Lord declared that his Spirit should not thus strive with men always; he would leave them to be hardened in sin, and ripened for destruction. This he determined on, because man was flesh: not only frail and feeble, but carnal and depraved; having misused the noble powers of his soul to gratify his corrupt inclinations. God sees all the wickedness that is among the children of men; it cannot be hid from him now; and if it be not repented of, it shall be made known by him shortly. The wickedness of a people is great indeed, when noted sinners are men renowned among them. Very much sin was committed in all places, by all sorts of people. Any one might see that the wickedness of man was great: but God saw that every imagination, or purpose, of the thoughts of man's heart, was only evil continually. This was the bitter root, the corrupt spring. The heart was deceitful and desperately wicked; the principles were corrupt; the habits and dispositions evil. Their designs and devices were wicked. They did evil deliberately, contriving how to do mischief. There was no good among them. God saw man's wickedness as one injured and wronged by it. He saw it as a tender father sees the folly and stubbornness of a rebellious and disobedient child, which grieves him, and makes him wish he had been childless. The words here used are remarkable; they are used after the manner of men, and do not mean that God can change, or be unhappy. Does God thus hate our sin? And shall not we be grieved to the heart for it? Oh that we may look on Him whom we have grieved, and mourn! God repented that he had made man; but we never find him repent that he redeemed man. God resolves to destroy man: the original word is very striking, 'I will wipe off man from the earth,' as dirt or filth is wiped off from a place which should be clean, and is thrown to the dunghill, the proper place for it. God speaks of man as his own creature, when he resolves upon his punishment. Those forfeit their lives who do not answer the end of their living. God speaks of resolution concerning men, after his Spirit had been long striving with them in vain. None are punished by the justice of God, but those who hate to be reformed by the grace of God.

Matthew Henry's Whole Bible Commentary

Verse 3

This comes in here as a token of God's displeasure at those who married strange wives; he threatens to withdraw from them his Spirit, whom they had grieved by such marriages, contrary to their convictions: fleshly lusts are often punished with spiritual judgments, the sorest of all judgments. Or as another occasion of the great wickedness of the old world; the Spirit of the Lord, being provoked by their resistance of his motions, ceased to strive with them, and then all religion was soon lost among them. This he warns them of before, that they might not further vex his Holy Spirit, but by their prayers might stay him with them. Observe in this verse,

I. God's resolution not always to strive with man by his Spirit. The Spirit then strove by Noah's preaching (1 Pt. 3:19, 20) and by inward checks, but it was in vain with the most of men; therefore, says God, He shall not always strive. Note, 1. The blessed Spirit strives with sinners, by the convictions and admonitions of conscience, to turn them from sin to God. 2. If the Spirit be resisted, quenched, and striven against, though he strive long, he will not strive always, Hos. 4:17. 3. Those are ripening apace for ruin whom the Spirit of grace has left off striving with.

II. The reason of this resolution: For that he also is flesh, that is, incurably corrupt, and carnal, and sensual, so that it is labour lost to strive with him. Can the Ethiopian change his skin? He also, that is, All, one as well as another, they have all sunk into the mire of flesh. Note, 1. It is the corrupt nature, and the inclination of the soul towards the flesh, that oppose the Spirit's strivings and render them ineffectual. 2. When a sinner has long adhered to that interest, and sided with the flesh against the Spirit, the Spirit justly withdraws his agency, and strives no more. None lose the Spirit's strivings but those that have first forfeited them.

III. A reprieve granted, notwithstanding: Yet his days shall be one hundred and twenty years; so long I will defer the judgment they deserve, and give them space to prevent it by their repentance and reformation. Justice said, Cut them down; but mercy interceded, Lord, let them alone this year also; and so far mercy prevailed, that a reprieve was obtained for six-score years. Note, The time of God's patience and forbearance towards provoking sinners is sometimes long, but always limited: reprieves are not pardons; though God bear a great while, he will not bear always.
