I. We have an outline sketch of the herald and of his work. The voice of prophecy had fallen silent for four hundred years. Now, when it is once more heard, it sounds in exactly the same key as when it ceased. Its last word had been the prediction of the day of the Lord, and of the coming of Elijah once more. John was Elijah over again. There were the same garb, the same isolation, the same fearlessness, the same grim, gaunt strength, the same fiery energy of rebuke which bearded kings in the full fury of their self-will. Elijah, Ahab, and Jezebel have their doubles in John, Herod, and Herodias. The closing words of Malachi, which Matthew, singularly enough, does not quote, are the best explication of the character and work of the Baptist. His portrait is flung on the canvas with the same startling abruptness with which Elijah is introduced. Matthew makes no allusion to his relationship to Jesus, has nothing to say about his birth or long seclusion in the desert. He gives no hint that his vague expression 'in these days' covers thirty years. John leaps, as it were, into the arena full grown and full armed. His work is described by one word--'preaching'; out of which all modern associations, which have too often made it a synonym for long-winded tediousness and toothless platitudes, must be removed. It means proclaiming, or acting as a herald, and implies the uplifted voice and the brief, urgent message of one who runs before the chariot, and shouts, 'The king! the king!' His message is summed up in two sentences, two blasts of the trumpet: the call to repentance, and the rousing proclamation that the kingdom of heaven is at hand. In the former he but reproduces the tone of earlier prophecy, when he insists on a thorough change of disposition and a true sorrow for sin. But he advances far beyond his precursors in the latter, which is the reason for repentance. They had seen the vision of the kingdom and the King, 'but not nigh.' He has to peal into the drowsy ears of a generation which had almost forgotten the ancient hope, that it was at the very threshold. Like some solitary stern crag which catches the light of the sun yet unrisen but hastening upwards, long before the shadowed valleys, John flamed above his generation all aglow with the light, as the witness that in another moment it would spring above the eastern horizon. But he sees that this is no joyful message to them. Nothing is more remarkable in his preaching than the sombre hues with which his expectation of the day of the Lord is coloured. 'To what purpose is the day of the Lord to you? It is darkness and not light'; it is to be judgment, therefore repentance is the preparation.
