We need repeated preaching, because by nature we will never repent and believe. We will ‘move on’ from the simple gospel of daily repentance, daily taking up the cross, daily faith, to a supposed higher life, a more sophisticated life, some kind of super-spiritual life in which repentance and faith are too ordinary and simple to be practiced. This is what will happen unless we sit under faithful preaching. We need the urgency of a city watchman to cry out, ‘Listen to the sound of the trumpet!’ (Jer. 6:17)

The urgency of faith means we need to preach with urgent passionate clarity, clear urgent passion, and passionate clear urgency.
