We are all, at times, unconscious prophets. - Charles Spurgeon

Oh, my brothers and sisters in Christ, if sinners will be damned, at least let them leap to hell over our bodies; and if they will perish, let them perish with our arms about their knees, imploring them to stay, and not madly to destroy themselves. If hell must be filled, at least let it be filled in the teeth of our exertions, and let not one go there unwarned and unprayed for.

This is faith, receiving the truth of Christ; first knowing it to be true, and then acting upon that belief.

The preacher's work is to throw sinners down in utter helplessness, that they may be compelled to look up to Him who alone can help them.
