I have seen it stated that the oyster mend its shell with a pearl. Where the ugly wound was, there comes, with the healing, not a scar, but a pearl. The same is true in human souls when divine grace heals the wounds of sins. Sins that we truly repent of become pearls in the character. It is the experience of all who grow into Christ like nobleness, that many of the golden lines of their later lives have been wrought out through their regrets and their repenting of wrong doings. Someone says, “The besetting sin may become the guardian angel.”
