(9) Know ye not that the unrighteous . . .?--The force of this question comes out more strikingly in the original, where the word rendered "unrighteous" is the same as "ye do wrong" of 1Corinthians 6:8. "You do wrong, apparently forgetting that no wrongdoers shall inherit God's kingdom."

Be not deceived.--There was great danger of their being led to think lightly of sins which were daily committed by those amongst whom they lived, hence these words of warning with which the sentence opens, as in 1Corinthians 15:33. The mention of gross sensual sins in connection with idolaters points to the fact that they were practically associated in the ritual of the heathen, which, of course, intensified the danger against which the Apostle warns the Corinthians. The prevalence of such scandalous crimes in the heathen world is constantly referred to in the Epistles to Gentile churches (Romans 13:13; Galatians 5:19-20; 1Timothy 1:9-10; Titus 1:12).

Verse 9. - Know ye not; rather, Or know ye not, as before. Are you defying God, or does your sin arise from mere ignorance? The unrighteous; better, that wrong doers, the verb being the same as "ye do wrong" in ver. 8. Perhaps the Corinthians thought that they would be saved by the mere fact of having been admitted into God's kingdom (the Christian Church in all its highest privileges) by baptism. St. Paul here lays down, as distinctly as St. James does, that faith without works is dead, and privileges without holiness are abrogated. The spirit of his warning is the same as that of Jeremiah 7:4, "Trust ye not in lying words, saying, The temple of the Lord... are these;" or that of St. John the Baptist, "Say not unto yourselves, We be Abraham's sons." Christians have often been liable to the temptation of underrating the peril which results from the falling asunder of action from knowledge. There can be no greater danger than that of talking slightingly of "mere morality." Religion is not an outward service, but a spiritual life manifested by a holy living. Be not deceived. So our Lord says," Let no man deceive you" (Mark 13:5; comp. 1 John 3:7). St. Paul uses the warning very solemnly again in 1 Corinthians 15:33 and Galatians 6:7, and St. James in James 1:16. The self deception of merely verbal orthodoxy is the most dangerous of all. Neither fornicators. The first four classes of sinners were specially prevalent at Corinth, where, indeed, impurity formed part of the recognized cult of the local Aphrodite (comp. 2 Corinthians 12:21). Lists of these "works of the flesh," which were the all but universal curse and stain of heathendom, occur also in Galatians 5:19-21; 1 Timothy 1:10, etc.; Colossians 3:5-7.

6:9-11 The Corinthians are warned against many great evils, of which they had formerly been guilty. There is much force in these inquiries, when we consider that they were addressed to a people puffed up with a fancy of their being above others in wisdom and knowledge. All unrighteousness is sin; all reigning sin, nay, every actual sin, committed with design, and not repented of, shuts out of the kingdom of heaven. Be not deceived. Men are very much inclined to flatter themselves that they may live in sin, yet die in Christ, and go to heaven. But we cannot hope to sow to the flesh, and reap everlasting life. They are reminded what a change the gospel and grace of God had made in them. The blood of Christ, and the washing of regeneration, can take away all guilt. Our justification is owing to the suffering and merit of Christ; our sanctification to the working of the Holy Spirit; but both go together. All who are made righteous in the sight of God, are made holy by the grace of God.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, Genesis 38:8.

Nor abusers of themselves with mankind; sodomites.
