Christians are so screwed up that…that they know they are screwed up! The only difference between a believer and a nonbeliever is that a Christian KNOWS THAT THEY NEED JESUS! Period.
Good works do not make someone a Christian. Going to church, serving the community, or reading the Bible does not make someone a Christian. Bowing at the feet of Jesus is the answer. The only answer.
In fact, look at the Bible, the righteous man, the good man, and the men of the church are condemned. The prostitute begging forgiveness, the sinner in repentance, they are saved.
Christians, more often than not, are the really big sinners.
This is not what the world thinks, but it is what Jesus says.
