Here he takes occasion to warn them against many heinous evils, to which they had been formerly addicted.

I.He puts it to them as a plain truth, of which they could not be ignorant, that such sinners should not inherit the kingdom of God. The meanest among them must know thus much, that the unrighteous shall not inherit the kingdom of God (Co1 6:9), shall not be owned as true members of his church on earth, nor admitted as glorious members of the church in heaven. All unrighteousness is sin; and all reigning sin, nay, every actual sin committed deliberately, and not repented of, shuts out of the kingdom of heaven. He specifies several sorts of sins: against the first and second commandments, as idolaters; against the seventh, as adulterers, fornicators, effeminate, and Sodomites; against the eighth, as thieves and extortioners, that by force or fraud wrong their neighbours; against the ninth, as revilers; and against the tenth, as covetous and drunkards, as those who are in a fair way to break all the rest. Those who knew any thing of religion must know that heaven could never be intended for these. The scum of the earth are no ways fit to fill the heavenly mansions. Those who do the devil's work can never receive God's wages, at least no other than death, the just wages of sin, Rom 6:23.

II.Yet he warns them against deceiving themselves: Be not deceived. Those who cannot but know the fore-mentioned truth are but too apt not to attend to it. Men are very much inclined to flatter themselves that God is such a one as themselves, and that they may live in sin and yet die in Christ, may lead the life of the devil's children and yet go to heaven with the children of God. But this is all a gross cheat. Note, It is very much the concern of mankind that they do not cheat themselves in the matters of their souls. We cannot hope to sow to the flesh and yet reap everlasting life.

III.He puts them in mind what a change the gospel and grace of God had made in them: Such were some of you (Co1 6:11), such notorious sinners as he had been reckoning up. The Greek word is tauta - such things were some of you, very monsters rather than men. Note, Some that are eminently good after their conversion have been as remarkably wicked before. Quantum mutatus ab illo! How glorious a change does grace make! It changes the vilest of men into saints and the children of God. Such were some of you, but you are not what you were. You are washed, you are sanctified, you are justified in the name of Christ, and by the Spirit of our God. Note, The wickedness of men before conversion is no bar to their regeneration and reconciliation to God. The blood of Christ, and the washing of regeneration, can purge away all guilt and defilement. Here is a rhetorical change of the natural order: You are sanctified, you are justified. Sanctification is mentioned before justification: and yet the name of Christ, by which we are justified, is placed before the Spirit of God, by whom we are sanctified. Our justification is owing to the merit of Christ; our sanctification to the operation of the Spirit: but both go together. Note, None are cleansed from the guilt of sin, and reconciled to God through Christ, but those who are also sanctified by his Spirit. All who are made righteous in the sight of God are made holy by the grace of God.

The unrighteous shall not inherit the kingdom - The unrighteous, αδικοι, those who act contrary to right, cannot inherit, for the inheritance is by right. He who is not a child of God has no right to the family inheritance, for that inheritance is for the children. If children, then heirs; heirs of God, and joint heirs with Christ, Rom 8:17. There are here ten classes of transgressors which the apostle excludes from the kingdom of God; and any man who is guilty of any one of the evils mentioned above is thereby excluded from this kingdom, whether it imply the Church of Christ here below, or the state of glory hereafter.

Several of the evils here enumerated will not bear to be particularly explained; they are, however, sufficiently plain of themselves, and show us what abominations were commonly practised among the Corinthians.

Know ye not that the unrighteous shall not inherit the kingdom of God?.... A way of speaking much like that in the Talmud, "know thou, that the world to come is not made but for the righteous?" (h) Without a righteousness there will be no entrance into the world of bliss and happiness hereafter; and this must be a better righteousness than what a sinful creature is capable of working out, and no other than the righteousness of Christ. It was a loss and want of righteousness that cast the angels down from heaven, and turned Adam out of paradise; and whoever of his posterity: are destitute of one, will fall short of enjoying the glory of God; for it is not agreeable to the holy nature of God, to his infinite justice and righteous law, to admit any into heaven without a righteousness: hence a judgment seat is erected, before which all must stand; and those that will be found without a righteousness, will be for ever excluded the kingdom of heaven; and could any unrighteous persons be received there, it would spoil the pleasure and happiness of the saints. Now this is said, partly to dissuade the Corinthians from going to law with each other before unrighteous persons, who have no right to the kingdom of God, and living and dying as they are, will have no share in it; and therefore since they are not to be fellow heirs and companions with them in another world, they should not bring their causes before them in this; and partly to reprove them for their injurious and unrighteous actions among themselves, their tricking and defrauding of one another, with other sins they were guilty of; which, if not repented of, would show, that notwithstanding their profession, they were destitute of the grace of God, were unfit to be in the kingdom of God, in a Gospel church state here below, and would be shut out of the kingdom of heaven hereafter.

Be not deceived imagining, that through your knowledge and profession you shall be saved, live as you will:

neither fornicators, such as are guilty of uncleanness with persons in a single state:

nor idolaters; who worship more gods than one, and not the true God; who do service to them that are not gods, and perform what the Jews call "strange service": and not only fall down to stocks and stones, but serve divers lusts and pleasures, the idols of their own hearts:

nor adulterers: such as have criminal conversation with persons in a married state:

nor effeminate; or "soft", or, as the Syriac renders it, "corrupters"; that is, of themselves, by voluntary pollution, such as are guilty of the sin of Onan, Gen 38:8.

Nor abusers of themselves with mankind; sodomites.
