In Paul's letter to the Ephesians, Chapter 5, he exhorts his Christian audience to remain pure and avoid lewd conduct. He says "Make no mistake about this: no fornicator, no unclean or lustful person has any inheritance in the kingdom of Christ and of God......These are sins which bring down God's wrath on the disobedient; therefore have nothing to do with them."
Paul is speaking to Christians in regards to other disobedient Christians. He does not identify the disobedient as unsaved or nonbelievers. Clearly, in our time, we know Christians guilty of sins such as these. Paul in effect said Christians such as these have no share in the kingdom at all. How do you reconcile this with your above statement?
