The call

“I don’t preach myself. I preach the call. The call comes from God and I’m just responding to a call. That keeps you humble. It ought to be our human desire to do something for God and be able to say that he used me. A cult leader preaches himself.”—Follow Me to Freedom: Leading As an Ordinary Radical by Shane Claiborne and John Perkins

Yep. If a person is preaching him/herself, you know there's a problem.
