Preaching is first of all a proclamation of the being of God . . . preaching worthy of the name starts with God and with a declaration concerning His being and power and glory. You find that everywhere in the New Testament. That was precisely what Paul did in Athens — “Him declare I unto you.” “Him”! Preaching about God, and contrasting Him with the idols, exposing the emptiness and the acuity and uselessness of idols.
