Revelation 21:21
21 And the twelve gates were twelve pearls; every several gate was of one pearl: and the street of the city was pure gold, as it were transparent glass.
Revelation 21:21. "And the street of the city was pure gold, like unto transparent glass." This does most livelily represent the perfect purity of that city and its inhabitants. In the most stately and magnificent cities in the world, however beautiful the buildings are, yet the streets are dirty and defiled, being made to be trodden under-foot; but the very streets of this heavenly city are so pure, that their being like pure gold does not sufficiently represent the purity of them, but they appear also like clear glass, or crystal. If there be the least dirt or defilement, it discovers itself in that which is transparent; but those golden streets appeared perfectly clear, without the least speck to lessen the transparency. Christ represents as though the saints that he has washed, though they are clean, yet while in this world have defiled feet, they need to be often washing their feet, but in that world their feet shall be perfectly pure, so as not at all to defile the streets. This is an evidence that what is treated of in those two last Chapter s of Revelations is the heavenly state of the church.
