The sun shall be no more thy light by day; neither for brightness shall the {t} moon give light to thee: but the LORD shall be to thee an everlasting light, and thy God thy glory.

(t) Signifying that all worldly means will cease, and that Christ will be all in all, as in Re 21:23,22:5.

Wesley's Notes

60:19 The sun - These shall not be esteemed in comparison of the spiritual light of the church; but here laid down for the churches comfort as the former was for her safety, so that God will not only be a shield, but a sun. The Lord - Christ shall scatter all darkness and ignorance, and this light shall not wax, and wane, and suffer eclipses, and settings, as the sun and moon do, but shall be constant, without shadow of change. The glory - Always ministering matter of glorying in him.

Jamieson-Fausset-Brown Bible Commentary

19. The sun and moon, the brightest objects by day and night, shall be eclipsed by the surpassing glory of God manifesting Himself to thee (Isa 30:26; Zec 2:5; Re 21:23; 22:5).

Matthew Henry's Concise Commentary

60:15-22 We must look for the full accomplishment in times and things, exceeding those of the Old Testament church. The nations and their kings shall lay themselves out for the good of the church. Such a salvation, such a redemption, shall be wrought out for thee, as discovers itself to be the work of the Lord. Every thing shall be changed for the better. In thy land shall no more be heard threats of those that do violence, nor complaints of those that suffer violence. Thy walls shall be means of safety, thy gates shall be written upon with praises to God. In the close of this chapter are images and expressions used in the description of the New Jerusalem, Re 21:23; 22:5. Nothing can answer to this but some future glorious state of the church on earth, or the state of the church triumphant in heaven. Those that make God their only light, shall have him their all-sufficient light. And the happiness shall know no change or alloy. No people on earth are all righteous; but there are no mixtures in heaven. They shall be wholly righteous. The spirits of just men shall there be made perfect. The glory of the church shall be to the honour of God. When it shall be finished, it will appear a work of wonder. It may seem too difficult to be brought about, but the God of almighty power has undertaken it. It may seem to be delayed and put off; but the Lord will hasten it in the time appointed by his wisdom, though not in the time prescribed by our folly. Let this hope cheer us under all difficulties, and stir us up to all diligence, that we may have an abundant entrance into this everlasting kingdom of our Lord and Saviour Jesus Christ.
