Jeremiah 28:15 Then said the prophet Jeremiah unto Hananiah the prophet, Hear now, Hananiah; The Lord hath not sent thee; but thou makest this people to trust in a lie.
Preachers that preach and convince people but who are not from God are nothing new. Here is Jeremiah telling another that he is not from God. He tells him that he is causing the people to believe a lie.
How many times we are stuck with preachers that tell lies. The bad thing is the people believe them.
There is only one way to be sure that your preacher is telling the truth. You must measure what He says by the Word of God.
