Matthew Henry Commentary 1 Corinthians 6:9-11

"Or know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with men, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God. And such were some of you: but ye were washed, but ye were sanctified, but ye were justified in the name of the Lord Jesus Christ, and in the Spirit of our God." — 1 Corinthians 6:9-11 (ASV)

The Corinthians are warned against many great evils, of which they had previously been guilty. There is much force in these inquiries when we consider that they were addressed to a people puffed up with the notion that they were superior to others in wisdom and knowledge. All unrighteousness is sin; all reigning sin, indeed, every actual sin, deliberately committed and not repented of, excludes from the kingdom of heaven.

Do not be deceived. People 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 due 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.
