"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 mankind," 1 Corinthians 6:9 KJV
We hear so many people say that God will allow everyone into the kingdom of heaven that He won't allow any to perish. People want to believe that God will bring everyone to salvation. It is true that God's Word says that God wishes that none should perish but He clearly states who won't enter into eternal salvation in the kingdom of God.
People can come to repentance and acceptance of Jesus as their Savior at any time of their life and enter into the kingdom of God.
Fornicators - people have sex outside of the bonds of marriage.
Idolaters - people who worship an idol or a physical object as a representation of a god.
Adulterers - married men and women who are cheating on their spouses. This can be an affair of the heart and mind - you don't have to be physically sexual with that person. So many married people are getting emotionally involved with people they have never met over the Internet. They are having affairs - they are committing adultery just the same as the man or woman who is in bed with someone other than their spouse and having sex.
Effeminate - having feminine qualities untypical of a man : not manly in appearance or manner. Effeminacy are traits in a human boy or man that are more often associated with feminine nature. The ancient Greeks described whole societies as effeminate if they were characterized by an acceptance of a lifestyle without question, people who yielded to this lifestyle with respectful submission, or autocratic political culture. Here, it was the form of sexual relationships, but not the fact of homosexual relations (which were not uncommon among Greek citizens who were men) that was critical to the sexual dimension of the term. The definition of effeminate has changed over the centuries. I dated a man who seemed to be effeminate and he wasn't gay. I was married to a man with effeminate mannerisms and men thought he was gay only he wasn't.
Abusers of themselves with mankind refers in some commentaries to homosexuality and masturbation. Also, Paul was referring to human sacrifices as well. People who abuse other people are included in this passage.
Paul listed sins that is not acceptable to God. There are more such as thieves, liars, drunkards, extortioners. Paul goes on to say in verse 11 "And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of God." As long as there is breath in you, you can repent and turn away from your sins, to be washed in the blood of Jesus the Christ - our Messiah - to be able to enter into the Kingdom of God.
