The Bible warns about false teachers, telling people it's OK to continue in sin.
Jude 1:3; Beloved, while I was making every effort to write you about our common salvation, I felt the necessity to write to you appealing that you contend earnestly for the faith which was once for all handed down to the saints.
Jude 1:4; For certain persons have crept in unnoticed, those who were long beforehand marked out for this condemnation, ungodly persons who turn the grace of our God into licentiousness and deny our only Master and Lord, Jesus Christ.
Jude 1:10; But these men revile the things which they do not understand; and the things which they know by instinct, like unreasoning animals, by these things they are destroyed.
Jude 1:11; Woe to them! For they have gone the way of Cain, and for pay they have rushed headlong into the error of Balaam, and perished in the rebellion of Korah.
Jude 1:14; It was also about these men that Enoch, in the seventh generation from Adam, prophesied, saying, "Behold, the Lord came with many thousands of His holy ones,
Jude 1:15; to execute judgment upon all, and to convict all the ungodly of all their ungodly deeds which they have done in an ungodly way, and of all the harsh things which ungodly sinners have spoken against Him."
2Pet 2:1; But false prophets also arose among the people, just as there will also be false teachers among you, who will secretly introduce destructive heresies, even denying the Master who bought them, bringing swift destruction upon themselves.
2Pet 2:2; Many will follow their sensuality, and because of them the way of the truth will be maligned;
2Pet 2:3; and in their greed they will exploit you with false words; their judgment from long ago is not idle, and their destruction is not asleep.
2Pet 2:10; and especially those who indulge the flesh in its corrupt desires and despise authority. Daring, self-willed, they do not tremble when they revile angelic majesties,
2Pet 2:11; whereas angels who are greater in might and power do not bring a reviling judgment against them before the Lord.
2Pet 2:12; But these, like unreasoning animals, born as creatures of instinct to be captured and killed, reviling where they have no knowledge, will in the destruction of those creatures also be destroyed,
2Pet 2:13; suffering wrong as the wages of doing wrong. They count it a pleasure to revel in the daytime. They are stains and blemishes, reveling in their deceptions, as they carouse with you,
2Pet 2:14; having eyes full of adultery that never cease from sin, enticing unstable souls, having a heart trained in greed, accursed children;
2Pet 2:15; forsaking the right way, they have gone astray, having followed the way of Balaam, the son of Beor, who loved the wages of unrighteousness;
2Pet 2:16; but he received a rebuke for his own transgression, for a mute donkey, speaking with a voice of a man, restrained the madness of the prophet.
2Pet 2:17; These are springs without water and mists driven by a storm, for whom the black darkness has been reserved.
2Pet 2:18; For speaking out arrogant words of vanity they entice by fleshly desires, by sensuality, those who barely escape from the ones who live in error,
2Pet 2:19; promising them freedom while they themselves are slaves of corruption; for by what a man is overcome, by this he is enslaved.
2Pet 2:20; For if, after they have escaped the defilements of the world by the knowledge of the Lord and Savior Jesus Christ, they are again entangled in them and are overcome, the last state has become worse for them than the first.
2Pet 2:21; For it would be better for them not to have known the way of righteousness, than having known it, to turn away from the holy commandment handed on to them.
2Pet 2:22; It has happened to them according to the true proverb, "A DOG RETURNS TO ITS OWN VOMIT," and, "A sow, after washing, returns to wallowing in the mire."
2Tim 4:3; For the time will come when they will not endure sound doctrine; but wanting to have their ears tickled, they will accumulate for themselves teachers in accordance to their own desires,
2Tim 4:4; and will turn away their ears from the truth and will turn aside to myths.
