Jeremiah 23:16-18
This is what the LORD Almighty says: “Do not listen to what the prophets are prophesying to you; they fill you with false hopes. They speak visions from their own minds, not from the mouth of the LORD. They keep saying to those who despise me, ‘The LORD says: You will have peace.’
And to all who follow the stubbornness of their hearts they say, ‘No harm will come to you.’ But which of them has stood in the council of the LORD to see or to hear his word? Who has listened and heard his word?

Is this happening now? Are pastors preaching prosperity and peace? Are they filling people with false hope telling the people that they will escape trials and tribulations?

God is saying through the prophet Jeremiah that these false prophets have not taken council from Him. They prophesied in their own power telling the people what they wanted to hear.

The book of Jude is filled with words concerning false prophets in his time and on into the future.

A great lesson to learn from all this is:
Don't take one person's opinion solely. Listen to good council but also read God's Word and let the Holy Spirit teach.
