…and sprinkled both the book, and all the people… – Hebrews 9:19

Have you had sprinkling with the precious blood, my hearer? If you have, you shall live for ever; but if you have not, the wrath of God abideth on you. Do you ask how you can have the blood of Christ sprinkled upon you? It cannot be done literally, but faith does it. Faith is the bunch of hyssop which we dip into the basin, and it sprinkles man’s conscience from bad works. You say you have been christened, confirmed, baptized; but, all these things together would not save one soul, much less all the multitudes who trust in them. They are not sufficient for the taking away of a single sin. But you always say your prayers, and you have family prayers, and you are honest, and so on. I know all this; but all these things you ought to have done, and they will not make amends for what you have not done. All the debt that you have paid will not discharge those that are still due. Know you not that saying of the Scriptures, “by the deeds of the law there shall no flesh be justified in His sight: for by the law is the knowledge of sin” You may work your fingers to the bone, but you can never weave a righteousness that shall cover your nakedness before God. The only hope of the sinner is to come and cast himself upon what Jesus Christ has done for him, depending upon the groans, and agonies, and death of the martyred Saviour, who stood for us and suffered in our stead, that we might escape the wrath of God.

Trust Christ, and you shall live. The bloody sacrifice of Calvary is the only hope of sinners. Look there, and you shall find the Star of peace guiding you to the everlasting day; but turn your backs upon Christ, and you have turned your back upon heaven, you have courted destruction, you have sealed your doom. It is by the sprinkling of the blood, then, that we are saved. ~ C.H. Spurgeon
