There are many teachers and doctrines that are of the Christian faith. It is very difficult to discern if the person is doing the sermon for money (profit) or if they are really speaking what thus saith the Lord. Can one trust a collar and who is ordanining these preachers who are now multi-millionaires. Is it wrong to be a preacher that lives in a mansion with a Bentley that flies a Jet?
2 Corinthians 11:3-
But I am afraid that just as Eve was deceived by the serpent's cunning, your minds may somehow be led astray from your sincere and pure devotion to Christ. For if someone comes to you and preaches a Jesus other than the Jesus we preached, or if you receive a different spirit from the one you received, or a different gospel from the one you accepted, you put up with it easily enough.
