Deadly serious 2 Peter 2:1,2,3 KJV

Deadly is right.

“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. 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?’ And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’ Matthew 7:21–23 (NKJV)

'You think that it is possible to believe that He rose from the dead on the third day, and then to hear Him say these words to you? I don't.
Jas 2:19, Lk 21:34

As a reminder Nihilo is number 10 on Satan, Inc. (TOL Heretics list) in the Religious Zealots (saved by works crowd) category.

I could tell there was a screw loose, but I couldn't work out which one.  You'd think that those who trust in works would work harder at ridding themselves of irreverence, vulgare talk and impiety? 
Matt. 11:28, 29
