The evangelist is to preach upon SIN: to define what sin (as distinct from crime) really is, to show wherein its infinite enormity consists; to trace out its manifold workings in the heart; to indicate that nothing less than eternal punishment is its desert.
Ah, and preaching upon sin—not merely uttering a few platitudes concerning it, but devoting sermon after sermon to explaining what sin is in the sight of God—will not make him popular nor draw the crowds, will it?
No, it will not, and knowing this, those who love the praise of men more than the approbation of God, and who value their salary above immortal souls, trim their sails accordingly. “But such preaching will drive people away!” We answer, better drive people away by faithful preaching than drive the Holy Spirit away by unfaithfully pandering to the flesh. The terms of Christ’s salvation are erroneously stated by the present-day evangelist.
