2. And he carried me away in the spirit unto a great and high mountain, and showed me that great city, the holy Jerusalem, descending out of heaven from God--21:10.
The phrase in the spirit here is the same expression as that used in chapter 1:10 and it did not refer to the Holy Spirit in either of the passages, but rather indicated the visional rapture in which John was shown these things. It was in the spirit--his own spirit--that he was carried away to the place where these things were unfolded to him in vision.
The visional point to which he was carried was a great and high mountain. This apocalyptic panorama was a part of the imagery of the exaltation of the Jerusalem Bride. The same metaphorical language was used by Isaiah in a prophetic description of the pre-eminence of the church in its spiritual elevation above the level of all institutions of men. “ The mountain of the Lord’ s house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.” (Isaiah 2:2) In the same figurative character and language, John was carried in spirit to the mountain. It was not a mere mountain upon which the church was to be established in Isaiah’ s prophecy, but in the top of the mountains; and it is altogether fitting that John should be transported in spirit to a great and high mountain to be shown the grandeur and glory of the triumphant church.
From this eminent visional peak John saw the holy Jerusalem descending. It was designated the holy Jerusalem in contrast with the harlot Jerusalem. No greater or more impressive attributive title could have been ascribed to the Bride of Christ than that of the Holy City Jerusalem.
In this vision of elevation the entranced Seer saw that great city descending--it had not already descended, the events were yet in process, but the end was in sight. It was about to be the culmination of the entire apocalypse.
The Holy City was descending out of heaven from God-- that is, the visional emergence of the Woman from that place prepared of God mentioned in chapter 12:6, and compared with Matthew 24:16 in the comments in chapter twelve on these two related passages. The holy city, the church, was seen descending from God--that is, from the place prepared of God where God had protected her and preserved her in that period of tribulation. Upon the lofty mountain height, from a position where the Seer could descry the distant descent of the marvellous City, as if to discover by the eye an object at far focus and observe its approach, this vision of the New Jerusalem was unfolded to the revelator.
