How about the people that read the Bible and don't listen to God?
Many "religious" people are basically frauds. They take the parts of the Bible that suit them and ignore the really important stuff.
Jesus said, "Many are called, but few are chosen."
This is the most damning of all in my opinion:
21 Not everyone who says to Me, Lord, Lord, shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name? 23 And then I will declare to them, I never knew you; depart from Me, you who practice lawlessness!
Just because someone says they are believers of God, doesn't mean they really are. I am a follower of Jesus Christ. The proof of that is in my life. My actions alone.
The fool has said in his heart,
There is no God.
Peace. Let the flaming begin....
