How to tell if someone is a false teacher?
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.
Do they use grace as a license to sin? ( and thereby deny Jesus )
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 1:12; These are the men who are hidden reefs in your love feasts when they feast with you without fear, caring for themselves; clouds without water, carried along by winds; autumn trees without fruit, doubly dead, uprooted;
Jude 1:13; wild waves of the sea, casting up their own shame like foam; wandering stars, for whom the black darkness has been reserved forever.
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."
Jude 1:17; But you, beloved, ought to remember the words that were spoken beforehand by the apostles of our Lord Jesus Christ,
Jude 1:18; that they were saying to you, "In the last time there will be mockers, following after their own ungodly lusts."
Jude 1:19; These are the ones who cause divisions, worldly-minded, devoid of the Spirit.
Jude 1:20; But you, beloved, building yourselves up on your most holy faith, praying in the Holy Spirit,
Jude 1:21; keep yourselves in the love of God, waiting anxiously for the mercy of our Lord Jesus Christ to eternal life.
Are they telling you it's OK to be "following after their own ungodly lusts". (God doesnt care about sin)
It says here keep "yourselves" in the love in God, how do we do that?
John 14:21; "He who has My commandments and keeps them is the one who loves Me; and he who loves Me will be loved by My Father, and I will love him and will disclose Myself to him."
John 15:10; "If you keep My commandments, you will abide in My love; just as I have kept My Father's commandments and abide in His love.
What did even Paul say about this?
1Cor 7:19; Circumcision is nothing, and uncircumcision is nothing, but what matters is the keeping of the commandments of God.
Again how to spot these people...
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 2:4; For if God did not spare angels when they sinned, but cast them into hell and committed them to pits of darkness, reserved for judgment;
2Pet 2:5; and did not spare the ancient world, but preserved Noah, a preacher of righteousness, with seven others, when He brought a flood upon the world of the ungodly;
2Pet 2:6; and if He condemned the cities of Sodom and Gomorrah to destruction by reducing them to ashes, having made them an example to those who would live ungodly lives thereafter;
Are they teaching you it's OK to "follow their sensuality" (again, God is ok with sin according to them)
2Pet 2:9; then the Lord knows how to rescue the godly from temptation, and to keep the unrighteous under punishment for the day of judgment,
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,
Are they teaching it's OK to "indulge in the flesh in it's corrupt desires".
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;
Are they teaching you God is OK if you "never cease from sin".
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.
Are they promising you "freedom" while they themselves are still slaves of corruption? If so, if this is what they teach. They are a false teacher and false prophet.
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.
People want to have their ears tickled. Which do you think people would rather hear? God is OK with however you live and whatever you want to do.
Or God requires obedience. If they're telling God doesn't care how you live, they're a false teacher.
1Jn 2:3; By this we know that we have come to know Him, if we keep His commandments.
1Jn 2:4; The one who says, "I have come to know Him," and does not keep His commandments, is a liar, and the truth is not in him;
1Tim 1:7; wanting to be teachers of the Law, even though they do not understand either what they are saying or the matters about which they make confident assertions.
