541 Sing, O barren one who did not bear; burst into song and shout, you who have not been in labor! For the children of the desolate woman will be more than the children of her that is married, says the Lord. 2 Enlarge the site of your tent, and let the curtains of your habitations be stretched out; do not hold back; lengthen your cords and strengthen your stakes. 3 For you will spread out to the right and to the left, and your descendants will possess the nations and will settle the desolate towns.
Matthew Henry's Commentary on Isaiah 54:1-3
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.
