The leopard has spots and cannot change them.
The leper has spots and cannot cure them.
The sinner has spots which are not those of God’s children. Spots mark the sinner.
The mere professor steals into the circle of God s children, and is a spot in the feast of charity a blot and blemish. He has no right to be there.
The offerings in the Jewish Ritual had to be without spot or blemish.
Christ offered Himself without spot unto God. His was “the precious blood as of a lamb without blemish and without spot" by which the true believer knows that he was "redeemed from his vain conversation," so that, as Christ regards such an one, He can say,
"Thou art all fair, my love: there is no spot in thee."
And again, on the soon-coming day of His glory, He will present to Himself that Church for which He gave Himself—"a glorious Church without spot or wrinkle or any such thing, but holy and without blemish"—the trophy of grace and the triumph of redemption by the blood that is infinitely precious, and well able to cleanse away every spot from the most leprous of sinners, and qualify him, thus cleansed, to "enter the Holiest of all" as a purged and happy worshipper.
