“The twelve gates were twelve pearls, each gate made of a single pearl” (Rev. 21:21a.)
In his book, SONGS OF HEAVEN, Robert E. Coleman tells about the process of an oyster making a pearl. Basically, a pearl is formed from an oyster’s secretion of liquid, issued to protect itself from a wound. Without a wound, there would be no pearl.
I like Coleman’s application as he reflects upon the gates of heaven, which are made of pearls. By the wounds of our savior, we in Christ will someday be blessed to see those gates.
