After so many centuries, the question is fresh to-day. For still the spirit of Christ is working in His world, openly, palpably, spreading blessings far and wide. It is exalting multitudes of ignoble lives by hopes that are profound, far-reaching, and sublime. When savage realms are explored, it is Christ Who hastens thither with His gospel, before the trader in rum and gunpowder can exhibit the charms of a civilization without a creed. In the gloomiest haunts of disease and misery, madness, idiotcy, orphanage, and vice, there is Christ at work, the good Samaritan, pouring oil and wine into the gaping wounds of human nature, acting quite upon His own authority, careless who looks askance, not asking political economy whether genuine charity is pauperisation, nor questioning the doctrine of development, whether the progress of the race demands the pitiless rejection of the unfit, and selection only of the strongest specimens for survival. That iron creed may be natural; but if so, ours is supernatural, it is a law of spirit and life, setting us free from that base and selfish law of sin and death. The existence and energy of Christian forces in our modern world is indisputable: never was Jesus a more popular and formidable claimant of its crown; never did more Hosannas follow Him into the temple. But now as formerly His credentials are demanded: what is His authority and how has He come by it? Now we say of modern as of ancient inquiries, that they are right; investigation is inevitable and a duty. But see how Jesus dealt with those men of old. Let us not misunderstand Him. He did not merely set one difficulty against another, as if we should start some scientific problem, and absolve ourselves from the duty of answering any inquiry until science had disposed of this. Doubtless it is logical enough to point out that all creeds, scientific and religious alike, have their unsolved problems. But the reply of Jesus was not a dexterous evasion, it went to the root of things, and, therefore, it stands good for time and for eternity. He refused to surrender the advantage of a witness to whom He was entitled: He demanded that all the facts and not some alone should be investigated. In truth their position bound His interrogators to examine His credentials; to do so was not only their privilege but their duty. But then they must begin at the beginning. Had they performed this duty for the Baptist? Who or what was that mysterious, lonely, stern preacher of righteousness who had stirred the national heart so profoundly, and whom all men still revered? They themselves had sent to question him, and his answer was notorious: he had said that he was sent before the Christ; he was only a voice, but a voice which demanded the preparation of a way before the Lord Himself, Who was approaching, and a highway for our God. What was the verdict of these investigators upon that great movement? What would they make of the decisive testimony of the Baptist?
