And almost all things are by the law purged with blood; and without shedding of blood is no remission. – Hebrews 9:22

Under the old figurative dispensation, blood was sure to greet your eyes. It was the one most prominent thing under the Jewish economy, scarcely a ceremony was observed without it. You could not enter into any part of the tabernacle, but you saw traces of the blood-sprinkling. Sometimes there were bowls of blood cast at the foot of the altar. The slaughter of animals was the manner of worship; the effusion of blood was the appointed rite, and the diffusion of that blood on the floor, on the curtains, and on the vestments of the priests, was the constant memorial…In every place, at every time, in every instance where sin had to be removed, blood must flow, life must be given.

We have all of us to take the offering which has already been presented, and to accept the sacrifice which Christ has, of Himself, made in our stead; there is now no cause or ground for exemption to any man or woman born, nor ever shall there be, either in this world or in that which is to come, -“Without shedding of blood, there is no remission.” Blood has been shed, and there is, therefore, hope concerning such a thing. Remission, notwithstanding the stern requirements of the law, is not to be abandoned in sheer despair. The word remission means the putting away of debts. Just as sin may be regarded as a debt incurred to God, so that debt may be blotted out, cancelled, and obliterated. The sinner, God’s debtor, may cease to be in debt by compensation, by full acquittance, and may be set free by virtue of such remission. Such a thing is possible. Glory be to God! the remission of all sin is possible to be obtained. God hath so declared it, and He will not be unfaithful to His word. ~ C.H. Spurgeon
