A witness is wanted in the period of ignorance and darkness. Such a witness is the moon, which reflects a borrowed portion of light from the sun, and so assures us of him; but when the sun itself arises, himself becomes invisible, and as not existing. His borrowed light also is temporary and changeable. It waxes and wanes, and is sometimes full, and round, and perfect almost as the sun himself; at other times it diminishes and decays, and dies away till it is invisible. So the prophets had the Holy Spirit by time and by measure; and sometimes they were bright and luminous, and shone, as it were, with a celestial and perfect brightness; but then at other times, again, the Spirit in them declined and departed, and left them only the dark lump, waiting till its office should again return, of reflecting some greater or less portion of the sun’s own proper rays, and invisible till illuminated. But when the sun itself arose upon the world, this should be the sign of him. The light by which he shone should be his own; and should be in himself, and inherent in him. When the Spirit of God should descend upon him; when the hitherto unembodied light should find this rest, and take this place and station--the embodied Sun of Righteousness, and the light and life, the Divinity itself should be incarnate--then, this Spirit of God, the Godhead itself so united to man, should be the sign of the expected Messiah and the witness himself become extinct, in this the last triumphant exercise of his office and witness, (S. R. Bosanquet.)
The witness of the light
Does the light then need that witness should be borne to it? Is not light its own evidence? Yes, if men have eyes to see; but because they lay in the darkness and slumber of sin, it was necessary to arouse them, and to give testimony to the true light, distinguishing it from all false lights that could only lure to death. In an obvious sense, “the law and the prophets” formed a great system of “witness” to the coming One Act_10:43; Rom_3:21-22); but it required completing, and John’s ministry was the completion of it--the grand close of the prophetic symphony. The morning star, day’s harbinger, bears witness of the sun, by shining in his light; and so also does the mountain top, kindled with the first rays of morning, to the dwellers in the deep valley beneath, or the far-stretching plain. But John’s testimony went beyond even this: he not merely preceded the Messiah, closing the prophetic line, but, having first aroused the nation by that cry, “Repent,” he actually introduced and named Him to Israel. (J. Culross, D. D.)
The force of testimony
Testimony is like an arrow shot from a longbow; the force of it depends on the strength of the hand that draws it. Argument is like an arrow from a cross-bow, which has equal force though shot by a child. (Lord Bacon.)
