Revelation 21:19-20 says, “The foundations of the wall of the city were adorned with every precious stone: the first foundation was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald; the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst.” And John saw New Jerusalem (Revelation 21:11) “Having the glory of God. Her light was like a most precious stone, like a jasper stone, as clear as crystal.”
Before Revelation 21 there are other mentions of precious stones. In 1 Peter 2:4 the Lord is “a living stone, rejected by men but with God chosen and precious” and in 2:6 He is “in Zion a cornerstone, chosen and precious.” In 1 Corinthians 3 we all are to participate in the New Testament building work by using gold, silver, and precious stones. On the one hand, Christ is the precious stone; on the other hand, we build with precious materials.
First Corinthians 3:12 says, “But if anyone builds upon the foundation gold, silver, precious stones…” In our natural being we are none of these materials. In 2 Corinthians 4:7 we are earthen (clay) vessels and Christ is the treasure in us; He makes us precious. The precious stones in New Jerusalem are developed through Christ being revealed in us (Galatians 1:15-16), we being rooted in Him (Colossians 2:7), Christ living in us and us living one with Him (Galatians 2:20), Christ being formed in us (4:19), and Christ making home in us (Ephesians 3:16-17). Lord, grant me grace to cooperate with Your living in me every day. Be the precious one in me!
