Revelation 9:21

21 And they did not repent of their murders or their sorceries or their sexual immorality or their thefts.

A. They did not repent. Remember, God gave them time. He gave them opportunity and encouraged them to make the changes needed. They refused.

B. NOTE: All church discipline involves not just a sin, like adultery or drunkenness, but the refusal to repent. If they refuse to repent, there is not option left for God. God cannot remain Holy (pure, untainted by sin) if he condones, tolerates and permits sin to continue.

C. God extends the list - Murder, sorcery, sexual immorality, and stealing. These are just sample lists, not the sum total of sins that condemn. See Romans 1:1-32 and Galatians 5:1-26 for longer lists.
