And we as Christians today, what are we saying? We are saying that we want reformation and we want revival, but still we are not preaching into this generation, stating the negative things that are necessary. If there is to be a constructive revolution in the orthodox, evangelical church, then like Jeremiah we must speak of the judgment of individual men great and small, of the church, the state, and the culture, for many of them have known the truth of God and have turned away from Him and His propositional revelation. God exists, He is holy, and we must know that there will be judgment. And like Jeremiah, we must keep on so speaking regardless of the cost to ourselves.
