What are the gates of the holy city made of?
The gates of the holy city are made of pure pearl. Every gate is a single pearl, as Scripture states. This solid pearl construction highlights the city's beauty. The streets are also pure gold, transparent as glass, but the gates themselves are pearl.
Les teaches that the gates of the holy city are made of pure pearl. He emphasizes that every gate is a single pearl, a solid pearl, which would require a very large oyster but will be beautiful. He contrasts this with the biggest pearl in the world that women have gone to great lengths to have. The city is also garnished with all manner of precious stones in its foundations, and its street is pure gold, transparent as glass. Les notes God is getting it all ready, if it isn't already ready.
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.
