Isaiah 54:1
1“Sing, barren, you who didn’t give birth! Break out into singing, and cry aloud, you who didn’t travail with child! For more are the children of the desolate than the children of the married wife,” says the LORD.
Sing, barren, you who didn’t give birth! Break out into singing, and cry aloud, you who didn’t travail with child! For more are the children of the desolate than the children of the married wife, says the LORD. Wesley: Sing—The prophet having largely discoursed of the sufferings of Christ, and of the blessed fruits thereof, and here foreseeing that glorious state of the church, he breaks forth into this song of triumph. And as the foregoing chapter literally speaks of Christ, so doth this of the church of Christ. This church, consisting at first of the Jews, and afterwards of the Gentiles, had been barren, till the coming of Christ. The desolate—The church of the Gentiles, which in the times of the Old Testament was desolate, does now bring forth to God a more numerous posterity than that of the Jews.
After 53, the church of Christ sings; Jews first, then more numerous Gentiles. Sing; barren; desolate has more children than the married. Shared christology: Wesley's foregoing chapter is Christ; this is his church. Paul takes this up in Galatians 4:27.
The barren one is told to shout for joy. Calvin: after having spoken of the death of Christ, he passes on with good reason to the Church; we cannot behold it in Christ if he be viewed by himself; we must come to his body, because Christ suffered for the Church, and not for himself. Thou barren, that didst not bear: he calls the Church barren, because no offspring could be expected from her so long as she groaned under wretched bondage; and even apart from her external wretchedness, everything was corrupted and defiled by superstitions. He calls the Church not merely barren but a widow. I prefer the more simple view: this extraordinary fertility of the Church will be at variance with what usually takes place, so that men may not judge of her condition by the ordinary course of nature; and yet I acknowledge that she was at that time in widowhood; God had actually divorced that nation by driving it into banishment. This punishment will be temporary.
“Singing”—from the Servant's death to the body; exile as widowhood, then a fertility that breaks nature's odds. Barren sings; more children. Compare 53:10's seed: the same offspring.
