False Shepherds give no warnings.

Jeremiah 23:16-40

16 Thus says the LORD of hosts:
“ Do not listen to the words of the prophets who prophesy to you.
They make you worthless;
They speak a vision of their own heart,
Not from the mouth of the LORD.
17 They continually say to those who despise Me,
‘ The LORD has said, “You shall have peace”
’;

And to everyone who walks according to the dictates of his own heart, they say,
‘ No evil shall come upon you.’”

False Shepherd say to those who are walking in darkness and call themselves "christians" ; "No evil shall come upon you."  "They are just 'carnal Christians.'"    Making them 'feel' comfortable in their sin.  No need to repent as long as I know I shall "have peace."  This lie was propagated from the very beginning as the serpent told Eve,  "You will surely not die."  She and Adam did die that day, Spiritually.
18 For who has stood in the counsel of the LORD,
And has perceived and heard His word?
Who has marked His word and heard it?
19 Behold, a whirlwind of the LORD has gone forth in fury—
A violent whirlwind!
It will fall violently on the head of the wicked.
20 The anger of the LORD will not turn back
Until He has executed and performed the thoughts of His heart.
In the latter days you will understand it perfectly.
21 “ I have not sent these prophets, yet they ran.
I have not spoken to them, yet they prophesied.
22 But if they had stood in My counsel, And had caused My people to hear My words, Then they would have turned them from their evil way And from the evil of their doings.

Note the False Shepherds do not stand in the counsel of God, they just repeat the things they have heard from other false shepherds. Copy and paste.  It is a whole lots easier than studying for myself.
23 “ Am I a God near at hand,” says the LORD,

“ And not a God afar off?
24 Can anyone hide himself in secret places,
So I shall not see him?” says the LORD;

“ Do I not fill heaven and earth?” says the LORD.
25 “I have heard what the prophets have said who prophesy lies in My name, saying, ‘I have dreamed, I have dreamed!’ 26 How long will this be in the heart of the prophets who prophesy lies? Indeed they are prophets of the deceit of their own heart, 27 who try to make My people forget My name by their dreams which everyone tells his neighbor, as their fathers forgot My name for Baal.
28 “ The prophet who has a dream, let him tell a dream;
And he who has My word, let him speak My word faithfully.
What is the chaff to the wheat?” says the LORD.
29 “ Is not My word like a fire?” says the LORD,

“ And like a hammer that breaks the rock in pieces?
We do not like to think of God's Word being a Fire and a Hammer.  We like to think of it as wet water noodle. It might sting a little when we get hit by it, but it could never do any real damage.
30 “Therefore behold, am against the prophets,” says the LORD, “who steal My words every one from his neighbor.
Jer 23:30 NLT  “Therefore,” says the Lord, “I am against these prophets who steal messages from each other and claim they are from me.
(Copy and Paste)  Simply repeating the same things I have heard other "pastors" say.  Just because another "pastor" said it, doesn't make it Biblical.  Just because your denomination says it, doesn't mean it is God's Word.   The Bible says to, "Study to show yourself approved by God" not to copy as fast as you can.  They forget we have the Holy Spirit as our Teacher.  I feel sorry for the guy who does study and he is a part of a denomination who is not rightly dividing the word.  He, if he wants to stay employed in that denomination, must agree with their stance or lose his position as a pastor.  Some pastors find truth and are willing to leave the denomination in order to take a stand for truth.  It takes guts to do what you know to be right.  AW Tozer said,  "The Saint must walk alone."  If you are going to stand for Righteousness, Holiness, and Actually doing the Word of God and not just professing it; You will have people against you because they have been deceived into thinking that mental assent is the same as faith.
31 Behold, I am against the prophets,” says the LORD, “who use their tongues and say, ‘He says.’ 32 Behold, I am against those who prophesy false dreams,” says the LORD, “and tell them, and cause My people to err by their lies and by their recklessness. Yet I did not send them or command them; therefore they shall not profit this people at all,” says the LORD.
33 “So when these people or the prophet or the priest ask you, saying, ‘What is the oracle of the LORD?’ you shall then say to them, ‘What oracle?’ I will even forsake you,” says the LORD. 34 “And as for the prophet and the priest and the people who say, ‘The oracle of the LORD!’ I will even punish that man and his house. 35 Thus every one of you shall say to his neighbor, and every one to his brother, ‘What has the LORD answered?’ and, ‘What has the LORD spoken?’ 36 And the oracle of the LORD you shall mention no more. For every man’s word will be his oracle, for you have perverted the words of the living God, the LORD of hosts, our God37 Thus you shall say to the prophet, ‘What has the LORD answered you?’ and, ‘What has the LORD spoken?’ 38 But since you say, ‘The oracle of the LORD!’ therefore thus says the LORD: ‘Because you say this word, “The oracle of the LORD!” and I have sent to you, saying, “Do not say, ‘The oracle of the LORD!’” 39 therefore behold, I, even I, will utterly forget you and forsake you, and the city that I gave you and your fathers, and will cast you out of My presence. 40 And I will bring an everlasting reproach upon you, and a perpetual shame, which shall not be forgotten.’”

What does God say about the False Teacher and those who would listen to them rather than listen to God's Words?

"I will even forsake you,” says the LORD"
"....you have perverted the words of the living God, the LORD of hosts, our God."
"I, even I, will utterly forget you and forsake you"
"I will bring an everlasting reproach upon you, and a perpetual shame, which shall not be forgotten."
James 3:1  "My brethren, let not many of you become teachers, knowing that we shall receive a stricter judgment."
Rev 22:19 "and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life..."   (OOPS, Apparently God did'n't know about Once Saved Always Saved)  OSAS)
Darryl, Why are you so hard on the False Teachers?  Shouldn't we show them love?
