2Cor 11:3
But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
13 For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.
14 And no marvel; for Satan himself is transformed into an angel of light.
15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
Romans 16
17 Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them.
18 For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
1 Timothy 6
3 If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;
4 He is proud, knowing nothing, but doting about questions and strifes of words, whereof cometh envy, strife, railings, evil surmisings,
5 Perverse disputings of men of corrupt minds, and destitute of the truth, $uppo$ing that gain i$ godline$$: from such withdraw thyself.
Acts 20
29 For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock.
30 Also of your own selves shall men arise, speaking perverse things, to draw away disciples after them.
Matt 24:4 And Jesus answered and said unto them, Take heed that no man deceive you.
5 For many shall come in my name, saying, I am Christ; and shall deceive many.
(Many HAVE come in the name of Jesus, saying that Jesus is the Christ, and by twisting His and the Apostle's doctrine, HAVE deceived many)
11 And many false prophets shall rise, and shall deceive many.
24 For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.
Revelation 2
20 Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols.
21 And I gave her space to repent of her fornication; and she repented not.
22 Behold, I will cast her into a bed, and them that commit adultery with her into great tribulation, except they repent of their deeds.
23 And I will kill her children with death; and all the churches shall know that I am he which searcheth the reins and hearts: and I will give unto every one of you according to your works.
(If we are deceived by false prophets, we will suffer God's judgment for it.)
Revelation 18
4 And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
5 For her sins have reached unto heaven, and God hath remembered her iniquities.
Jer 14:13 Then said I, Ah, Lord GOD! behold, the prophets say unto them, Ye shall not see the sword, neither shall ye have famine; but I will give you assured peace in this place.
(The false prophets taught OSAS/eternal security to the rebelious house of Israel!)
14 Then the LORD said unto me, The prophets prophesy lies in my name: I sent them not, neither have I commanded them, neither spake unto them: they prophesy unto you a false vision and divination, and a thing of nought, and the deceit of their heart.
15 Therefore thus saith the LORD concerning the prophets that prophesy in my name, and I sent them not, yet they say, Sword and famine shall not be in this land; By sword and famine shall those prophets be consumed.
16 And the people to whom they prophesy shall be cast out in the streets of Jerusalem because of the famine and the sword; and they shall have none to bury them, them, their wives, nor their sons, nor their daughters: for I will pour their wickedness upon them.
Jer 23:9 Mine heart within me is broken because of the prophets...
10 ...their course is evil, and their force is not right.
11 For both prophet and priest are profane; yea, in my house have I found their wickedness, saith the LORD.
12 Wherefore their way shall be unto them as slippery ways in the darkness: they shall be driven on, and fall therein: for I will bring evil upon them, even the year of their visitation, saith the LORD.
13 And I have seen folly in the prophets of Samaria; they prophesied in Baal, and caused my people Israel to err.
14 I have seen also in the prophets of Jerusalem an horrible thing: they commit adultery, and walk in lies: they strengthen also the hands of evildoers, that none doth return from his wickedness; they are all of them unto me as Sodom, and the inhabitants thereof as Gomorrah.
15 Therefore thus saith the LORD of hosts concerning the prophets; Behold, I will feed them with wormwood, and make them drink the water of gall: for from the prophets of Jerusalem is profaneness gone forth into all the land.
16 Thus saith the LORD of hosts, Hearken not unto the words of the prophets that prophesy unto you: they make you vain: they speak a vision of their own heart, and not out of the mouth of the LORD.
17 They say still unto them that despise me, The LORD hath said, Ye shall have peace; and they say unto every one that walketh after the imagination of his own heart, No evil shall come upon you.
(They taught OSAS)
21 I have not sent these prophets, yet they ran: I have not spoken to them, yet they prophesied.
25 I have heard what the prophets said, that prophesy lies in my name, saying, I have dreamed, I have dreamed.
26 How long shall this be in the heart of the prophets that prophesy lies? yea, they are prophets of the deceit of their own heart
27 Which think to cause my people to forget my name...
(His name is called "the WORD of God" Rev 19:13. False prophets want people to forget God's Word and embrace THEIR word as if it is from God)
