The stones of the city –
I want to show you something remarkable that is recorded in the book of Revelation. What it shows is God is the only one who could know these things at the time they were written.
In Revelation 21:19 it tells us “the foundations of the wall of the city called New Jerusalem are garnished with all manner of precious stones. The first foundation was jasper; the second, sapphire; the third, a chalcedony; the fourth, an emerald; The fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, a topaz; the tenth, a chrysoprasus; the eleventh, a jacinth; the twelfth, an amethyst.” What you discover about these twelve stones is they are anisotropic jewels as distinct from Diamonds and rubies that are isotropic jewels. When pure light shines through a slither of the twelve stones that will make up the city of the New Jerusalem, they will show all the colors of the rainbow, because they are anisotropic jewels, and respond this way to pure light. Pure light is light that is like a laser beam going in a straight line, and not from reflected light that comes from all different directions. When pure light strikes a slither of isotropic jewels they appear black showing no color at all. It is only in the last generation that scientists have discovered this feature. It is only since they have discovered this feature that anyone but God could have known what stones to choose that will have this affect. Imagine the color and patterns that will occur when the pure light of God shines through the city.
The stones chosen have all the colors of the spectrum? They were chosen because they react to pure light in this way. The Revelation was written around 90 AD sixty years after Christ died. Scientists have only just experimented to discover this feature of these stones. That means God is the only one who could have known what we consider to be a modern scientific discovery.
