I. God speaks and bids His servants speak (vs. 1, 2), That is a wonderfully tender word with which the silence and sadness of exile are broken. The inmost meaning of God's voice is ever comfort. What a world of yearning love there is, too, in the two little words 'my' and 'your'! The exiles are still His; He who has hidden His face from them so long is still theirs. And what was true of them is true of us; for sin may separate us from God, but it does not separate Him from us, and He still seeks to make us recognise the imperishable bond, which itself is the ground of both our comfort and of His will that we should be comforted. As the very first words go deep into the meaning of all God's voices, and unveil the permanence of His relation of love even to sinful and punished men, so the next disclose the tender manner of His approach to us, and prescribe the tone for all His true servants: 'Speak ye to the heart of Jerusalem,' with loving words, which may win her love; for is she not the bride of Jehovah, fallen though she be? And is not humanity the beloved of Jesus, in whom God's heart is unveiled that our hearts may be won? How shall human voices be softened to tenderness worthy of the message which they carry? Only by dwelling near enough to Him to catch the echoes, and copy the modulations, of His voice, as some birds are taught sweeter notes than their own. The prophet's charge is laid upon all who would speak of Christ to men. Speak to the heart, not only to the head or to the conscience. God beseeches in the person of His 'ambassadors.' The substance of the message may well find its way to the heart; for it is the assurance that the long, hard service of the appointed term of exile is past, that the sin which brought it about is forgiven, and, more wonderful and gracious still, that God's mercy reckons that the ills which followed on faithlessness have more than expiated it. We need not seek for any other explanation of these startling words than the exuberance of the divine pity, which 'doth not willingly afflict.' Of course, the captivity is in the foreground of the prophet's vision; but the wider sense of the prophecy embraces the worse captivity of sin under which we all groan, and the divine voice bids His prophets proclaim that Jehovah comes, to set us all free, to end the weary bondage, and to exact no more punishment for sins.
