It is not "the blood of the Lamb" as revealed in the word of God, but as applied to and sprinkled on the conscience, which answers the accusations of Satan. But we may observe that there is our coming unto "the blood of sprinkling," and there is "the blood of sprinkling" coming unto us.
The Apostle speaks, Hebrews 12:22-24: "Ye are come to the blood of sprinkling, which speaketh better things than that of Abel." This coming to the blood is the first step in gaining the victory. But in Christian warfare defeat generally, if not always, precedes conquest. It is not, therefore, so easy to overcome sin, death, and hell, which are all striving against us; and usually we never look to the right quarter for help until well-nigh all hope is gone. The first gleam generally comes from a view of "the blood of the Lamb," as it were, in the distance. The lighthouse casts its glimmering rays far over the wide waste of waters, to guide into harbour the storm-tossed mariner; so, when there is a view in the soul of "the blood of the Lamb," even at a distance, it is a beacon light, which draws towards it the eyes and heart of those who are doing business "in deep waters." The light may not at first seem very bright or clear; but it is a day-star, heralding the rising of the sun. The Spirit shines on the word, and raises up faith in the soul to believe that the Lamb has been slain, that blood has been shed, that a sacrifice has been offered, and that "a new and living way" has been opened and consecrated "through the veil," the rent "flesh" of the Lord Jesus. This affords the accused soul some foothold on which it can stand and answer Satan's accusations. "True," he says, "I am a guilty wretch, a sinner, and the chief of sinners, for I have sinned against light, against convictions, against conscience, and the fear of God; my heart is altogether evil, my mind wholly corrupt, and my nature utterly depraved; I have never done any good thing; I am a wretch, and the worst of wretches, and I can never say anything too bad of myself, nor others of me; but, with all that, the Lamb of God hath shed his precious blood, and that blood 'cleanseth from all sin.'"
"When the enemy comes in like a flood, the Spirit of the Lord," we read, "shall lift up a standard against him"—the blood-stained flag of the crucified Redeemer; and to come for refuge under this banner dipped in blood is to make head against Satan. Still, the victory is not fully gained. It is only when there is a coming of the blood into the heart, a sprinkling of it on the conscience, a manifestation and application of it to the soul, that Satan is effectually put to flight.
