Jeremiah 6 is not written to us. Here are the beginning verses:
“Flee for safety, people of Benjamin!
Flee from Jerusalem!
Sound the trumpet in Tekoa!
Raise the signal over Beth Hakkerem!
For disaster looms out of the north,
even terrible destruction.
2 I will destroy Daughter Zion,
so beautiful and delicate.
3 Shepherds with their flocks will come against her;
they will pitch their tents around her,
each tending his own portion.”
Verse 16 is directed to the inhabitants of Jerusalem, giving instruction to avoid the judgment to come upon them. It is written to a city which is idolatrous, to instruct them to find the old paths of faithfulness to God. But they refused:
"I appointed watchmen over you and said,
‘Listen to the sound of the trumpet!’
But you said, ‘We will not listen.’
18 Therefore hear, you nations;
you who are witnesses,
observe what will happen to them.
19 Hear, you earth:
I am bringing disaster on this people,
the fruit of their schemes,
because they have not listened to my words
and have rejected my law" (vv. 17-19).
This is not written to born again believers who have Christ as their Saviour. We who have received Christ have listened to His voice in the Gospel and have accepted God's moral law as revealing our sin in order to come to God's throne of Grace to find mercy.
We can't take a verse of Scripture out of its natural context and twist it to mean something for born again Christians when it was never intended as such.
Seeing that it was the word of the Lord that came to Jeremiah, the Holy Spirit had no problems dealing extensively with the problems of the day. Look at what the Lord says about the false prophets:
"This is what the Lord All-Powerful says:
“Don’t pay attention to what those prophets are saying to you.
They are trying to fool you.
They talk about visions their own minds made up,
not about visions from me.
17 They say to those who hate me:
‘The Lord says: You will have peace.’
They say to all those who are stubborn and do as they please:
‘Nothing bad will happen to you.’
18 But none of these prophets has stood in the meeting of angels
to see or hear the message of the Lord.
None of them has paid close attention to his message.
19 Look, the punishment from the Lord
will come like a storm.
His anger will be like a hurricane.
It will come swirling down on the heads of those wicked people.
20 The Lord’s anger will not stop
until he finishes what he plans to do.
When that day is over,
you will understand this clearly.
21 I did not send those prophets,
but they ran to tell their message.
I did not speak to them,
but they prophesied anyway.
22 But if they had stood in the meeting of angels,
they would have told my message to my people.
They would have turned the people from their evil ways
and from doing evil.
23 “I am a God who is near,” says the Lord.
“I am also a God who is far away.
24 No one can hide
where I cannot see him,” says the Lord.
“I fill all of heaven and earth,” says the Lord.
25 “I have heard the prophets who prophesy lies in my name. They say, ‘I have had a dream! I have had a dream!’ 26 How long will this continue in the minds of these lying prophets? They prophesy from their own wishful thinking. 27 They are trying to make the people of Judah forget me by telling each other these dreams. In the same way, their ancestors forgot me and worshiped Baal. 28 Is straw the same thing as wheat?” says the Lord. “If a prophet wants to tell about his dreams, let him! But let the person who hears my message speak it truthfully! 29 Isn’t my message like a fire?” says the Lord. “Isn’t it like a hammer that smashes a rock?
30 “So I am against the false prophets,” says the Lord. “They keep stealing words from each other and say they are from me. 31 I am against the false prophets,” says the Lord. “They use their own words and pretend it is a message from me. 32 I am against the prophets who prophesy false dreams,” says the Lord. “They mislead my people with their lies and false teachings! I did not send them or command them to do anything for me. They can’t help the people of Judah at all,” says the Lord.
33 “Suppose the people of Judah, a prophet, or a priest asks you: ‘Jeremiah, what is the message from the Lord?’ You will answer them and say, ‘You are a heavy load to the Lord, and I will throw you down, says the Lord.’ 34 A prophet or a priest or one of the people might say, ‘This is a message from the Lord.’ That person has lied, so I will punish him and his whole family. 35 This is what you will say to each other: ‘What did the Lord answer?’ or ‘What did the Lord say?’ 36 But you will never again say, ‘The message of the Lord,’ because the only message you speak is your own words. You have changed the words of our God, the living God, the Lord All-Powerful. 37 This is how you should speak to the prophets: ‘What answer did the Lord give you?’ or ‘What did the Lord say?’ 38 But don’t say, ‘The message from the Lord.’ If you use these words, this is what the Lord says: Because you called it a ‘message from the Lord,’ though I told you not to use those words, 39 I will pick you up and throw you away from me, along with Jerusalem, which I gave to your ancestors and to you. 40 And I will make a disgrace of you forever; your shame will never be forgotten.” (Jeremiah 23:16-39).
Although this was what the Lord said to Judah through Jeremiah, it is written for our education as well. It shows the Lord's attitude toward false prophets. If Jeremiah was prophesying about the modern Charismatic prophets and those who have prophetic websites and Youtube channels, he would be saying exactly the same things.
