My dear fellow pastor, we should all heed these words—
“…If some preachers would refrain from rhetoric and tell their plain unvarnished tale, they would succeed better than they do now. Do you think that God meant his ministers to kill themselves in order come out on Sundays with one or two splendid displays of ‘intellect’ and eloquence? Surely this is not God’s way of doing things. I do not believe that Paul ever preached a fine sermon, or that Peter ever dreamed of any display of intellect. I asked the other day of one who had heard a sermon if it was likely that sinners would be converted by it. He said, ‘Oh no; by no means; but it was an intellectual treat.’ Is there anywhere in the Bible a word about intellectual treats, or anything approximating to such an idea?”
I’m not sure I can add much to this advice from the “prince of preachers” except to say, preach to glorify God, not to impress your earthly audience. Jesus said if we would lift Him up, He will draw everyone to Himself.
