1 Corinthians 5:9-11 (NIV) 9 I have written you in my letter not to associate with sexually immoral people-- 10 not at all meaning the people of this world who are immoral, or the greedy and swindlers, or idolaters. In that case you would have to leave this world. 11 But now I am writing you that you must not associate with anyone who calls himself a brother but is sexually immoral or greedy, an idolater or a slanderer, a drunkard or a swindler. With such a man do not even eat.
Romans 1:21 (NIV) For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.
Jude 1:4 (NIV) For certain men whose condemnation was written about long ago have secretly slipped in among you. They are godless men, who change the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.
It is easy to see that the moral sense has been bred out of certain sections of the population, like the wings have been bred off certain chickens to produce more white meat on them. This is a generation of wingless chickens. —Flannery O'Connor
