Whoever says, “I know him,” but does not do what he commands is a liar, and the truth is not in that person.

2 Timothy 3:5-8 NIV
having a form of godliness but denying its power. Have nothing to do with such people. They are the kind who worm their way into homes and gain control over gullible women, who are loaded down with sins and are swayed by all kinds of evil desires, always learning but never able to come to a knowledge of the truth. Just as Jannes and Jambres opposed Moses, so also these teachers oppose the truth. They are men of depraved minds, who, as far as the faith is concerned, are rejected.

Ephesians 5:6 NIV
Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient.

Isaiah 29:13 NIV
The Lord says: “These people come near to me with their mouth and honor me with their lips, but their hearts are far from me. Their worship of me is based on merely human rules they have been taught.

Jude 1:4 NIV
For certain individuals whose condemnation was written about long ago have secretly slipped in among you. They are ungodly people, who pervert the grace of our God into a license for immorality and deny Jesus Christ our only Sovereign and Lord.
