There is something very impressive in the abrupt bursting in of this second voice, all unnamed. It is the reverberation, as it were, of the former, giving the preparation on the side of man for the coming of Jehovah. Israel in bondage in Egypt had been delivered by Jehovah marching through the wilderness, a wilderness stretched between Babylon and Jerusalem; these supply the scenery, so to speak; but the scenery is symbolic, and the call is really one to prepare the way of the Lord in the wilderness of human sin, by raising up the cast-down by reason of transgressions or sorrows, to subdue lofty thoughts and self-sufficiency by humble self-abnegation, to make the crooked things' or rugged things' straight or smooth, and the rough ground where heights were tumbled on heights a deep valley, by forsaking evil.
The moral preparation, not the physical, is meant. It was fitting that the road for such a coming should be prepared. But the coming was not so contingent on the preparation that the glory of the Lord' would not be revealed' unless men made a highway for Him. True, that the revelation of His glory to the individual soul must be preceded by such a preparation; but that raising of abjectness and levelling of loftiness needs some perception of Him ere it can be done by man. Christ must come to the heart before the heart can be prepared for His coming. John the Baptist came crying in the wilderness, but his fiery message did little to cast up a highway for the footsteps of the King. John's immovable humility pierced to the very heart of the prophecy when he answered the question Who art thou?' with I am a voice. The voice was unnamed; why, what does it matter who I am?'
The substance and the range of the coming manifestation are next defined. It is to be the revelation of the glory of the Lord,' and to be for all mankind, not for Israel only. That lowly life and that shameful death were a strange revelation of God's glory. If they revealed it, then it cannot consist in power or any attributes, but in love, pity, and long suffering. Love is the divinest thing in God. The guarantee for all lies simply here, that God has spoken it. It is because the unnamed herald's ear has heard the divine voice uttering the gracious assurances of Isaiah 37:1, that his voice is lifted up in the commands and assurances of Isaiah 37:4. Absolute faith in God's utterances, however they seem to transcend experience, is wisdom and duty.
