4 Have no fear; for you will not be shamed or without hope: you will not be put to shame, for the shame of your earlier days will go out of your memory, and you will no longer keep in mind the sorrows of your widowed years. 5 For your Maker is your husband; the Lord of armies is his name: and the Holy One of Israel is he who takes up your cause; he will be named the God of all the earth.
6 For the Lord has made you come back to him, like a wife who has been sent away in grief of spirit; for one may not give up the wife of one's early days.
Matthew Henry's Commentary on Isaiah 54:4-6
Commentary on Isaiah 54:1-5
(Read Isaiah 54:1-5)
Observe the low state of religion in the world, for a long time before Christianity was brought in. But by preaching the gospel, multitudes were converted from idols to the living God. This is matter of great rejoicing to the church. The bounds of the church were extended. Though its state on earth is but mean and movable, like a tent or tabernacle, it is sometimes a growing state, and must be enlarged as the family increases. But the more numerous the church grows, the more she must fortify herself against errors and corruptions. Thy Maker is thy Husband. Christ is the Holy One of Israel, the Mediator of the covenant made with the Old Testament church. Long he had been called the God of Israel; but now he shall be called the God of the whole earth. And he will cleanse from sin, and cause every true believer to rejoice in this sacred union. We never can enough admire this mercy, or duly value this privilege.
Commentary on Isaiah 54:6-10
(Read Isaiah 54:6-10)
As God is slow to anger, so he is swift to show mercy. And how sweet the returns of mercy would be, when God should come and comfort them! He will have mercy on them. God's gathering his people takes rise from his mercy, not any merit of theirs; and it is with great mercies, with everlasting kindness. The wrath is little, the mercies great; the wrath for a moment, the kindness everlasting. We are neither to despond under afflictions, nor to despair of relief. Mountains have been shaken and removed, but the promises of God never were broken by any event. Mountains and hills also signify great men. Creature-confidences shall fail; but when our friends fail us, our God does not. All this is alike applicable to the church at large, and to each believer. God will rebuke and correct his people for sins; but he will not cast them off. Let this encourage us to give the more diligence to make our calling and election sure.
