THE BUILDING OR MATERIAL OF THE CITY.

(18) And the building of the wall . . .--Or, And the building-work (or, the masonry, so Alford) of the wall of it was jasper, and the city was pure gold, like pure glass. The general aspect of the city was jasperlike, because the material of the wall was of the jasper stone. On this stone, see Note on Revelation 4:3, and on Revelation 21:11 above. The city was gold. On the meaning of the gold see Note on Revelation 21:15 and on Revelation 3:18. To what has been said may be added the following:--"Gold has an inalienable reference to the sun itself, consequently, to the symbol of the face of God, or Christ, i.e., to the manifestation of God's love" (Lange).

The wealth of heaven is love; love is the circulating medium of all holy activity and of all holy work: all who dwell within the heavenly city are encompassed by it; all who tread the streets of that city move along the ways of love; no dimness or obscuring motives of self-interest mar its lustre--the gold is clear as pure glass.

Verse 18. - And the building of the wall of it was of jasper: and the city was pure gold, like unto clear glass; pure glass. The exceeding brightness and purity is the idea contained in both expressions - the light of ver. 11, which is there associated with jasper and crystal. (On "jasper," see on ver. 11 and Revelation 4:3.) The whole description is, of course, typical, not literal.

21:9-21 God has various employments for his holy angels. Sometimes they sound the trumpet of Divine Providence, and warn a careless world; sometimes they discover things of a heavenly nature of the heirs of salvation. Those who would have clear views of heaven, must get as near to heaven as they can, on the mount of meditation and faith. The subject of the vision is the church of God in a perfect, triumphant state, shining in its lustre; glorious in relation to Christ; which shows that the happiness of heaven consists in intercourse with God, and in conformity to him. The change of emblems from a bride to a city, shows that we are only to take general ideas from this description. The wall is for security. Heaven is a safe state; those who are there, are separated and secured from all evils and enemies. This city is vast; here is room for all the people of God. The foundation of the wall; the promise and power of God, and the purchase of Christ, are the strong foundations of the safety and happiness of the church. These foundations are set forth by twelve sorts of precious stones, denoting the variety and excellence of the doctrines of the gospel, or of the graces of the Holy Spirit, or the personal excellences of the Lord Jesus Christ. Heaven has gates; there is a free admission to all that are sanctified; they shall not find themselves shut out. These gates were all of pearls. Christ is the Pearl of great price, and he is our Way to God. The street of the city was pure gold, like transparent glass. The saints in heaven tread gold under foot. The saints are there at rest, yet it is not a state of sleep and idleness; they have communion, not only with God, but with one another. All these glories but faintly represent heaven.And the building of the wall of it was of jasper,.... Which is expressive of the impregnableness, duration, brightness, and glory of salvation by Christ, the jasper being a very hard, durable, and bright stone; and salvation can never be made void, and of none effect; it will last for ever, and in this state will come forth as light, and as a lamp that burneth; it is represented by the same precious stone as God and Christ themselves are; see Revelation 4:2. And the city was pure gold, like unto clear glass; it was made or built of gold; its parts, buildings, houses, and palaces, were all of gold, and that the best; and it was like to transparent glass; that is, either the city, as most copies read, or the gold; for the Alexandrian copy reads, and so the Vulgate Latin version; the gold of which it was is different from common gold; and as this city, the new Jerusalem, designs the saints, the precious sons of Zion, comparable to fine gold, the inhabitants of the new earth; this denotes the solidity, excellency, and preciousness of them, the rich and happy state they will be in, as well as their purity and freedom from all sin and corruption, and the clear knowledge of things they themselves will have, and others will have of them; their hearts and actions will be open to all; nor will this gold have any rust upon it any more, or ever be changed, and become dim.
