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.

The image is appropriate, as the tabernacle was the symbol of the old Israelitish Church (see on [855]Isa 33:20).
