'Denying' in the Bible

instructing us to the intent that, denying ungodliness and worldly lusts, we would live soberly, righteously, and godly in this present world;

But false prophets also arose among the people, as false teachers will also be among you, who will secretly bring in destructive heresies, denying even the Master who bought them, bringing on themselves swift destruction.

For there are certain men who crept in secretly, even those who were long ago written about for this condemnation: ungodly men, turning the grace of our God into indecency, and denying our only Master, God, and Lord, Jesus Christ.
