I found this to be so beautiful, I had to share it.
"The pearl is itself an emblem of redemption. It originates through specially strong secretion of mother of pearl by the pearl shell-fish as a reaction against injury from without, as by the inrush of inanimate objects, conferva (threads of seaweed), water-mites and the like. It is thus the answer of a wounded life to injury from without. So also the opening of the pearly gates of heaven is the answer of the fatally wounded life of the Redeemer to the sin at Golgotha, even the murder of Himself, the Son of God."
