Again, the pastor when facing his congregation on Sunday morning, dare not think of the effect his sermon may have on his job, his salary or his future relation to the church. Let him but worry about tomorrow and he becomes a hireling and not a true shepherd of the sheep. No man is a good preacher who is not willing to lay his future on the line every time he expounds the Word. He must let his job and his reputation ride on each and every sermon or he has no right to think that he stands in the prophetic tradition.  –A. W. Tozer, The Size of the Soul, p. 147
