IV. The means by which this shall be brought about: Out of Zion shall go forth the law, the New-Testament law, the law of Christ, as of old the law of Moses from Mount Sinai, even the word of the Lord from Jerusalem. The gospel is a law, a law of faith; it is the word of the Lord; it went forth from Zion, where the temple was built, and from Jerusalem. Christ himself began in Galilee, Matt. iv. 23; Luke xxiii. 5. But, when he commissioned his apostles to preach the gospel to all nations, he appointed them to begin in Jerusalem, Luke xxiv. 47. See Rom. xv. 19. Though most of them had their homes in Galilee, yet they must stay at Jerusalem, there to receive the promise of the Spirit, Acts i. 4. And in the temple on Mount Zion they preached the gospel, Acts v. 20. This honour was allowed to Jerusalem, even after Christ was crucified there, for the sake of what it had been. And it was by this gospel, which took rise from Jerusalem, that the gospel church was established on the top of the mountains. This was the rod of divine strength, that was sent forth out of Zion, Ps. cx. 2.
