According to the Law given to Moses by God Himself daily sacrifices of various animals were to be offered to God, both on a regular basis and on special occasions---the greatest of such special occasions is the Passover. There are multiple references to the instructions for the manner in which the animal is to be killed and specific instructions for what is to be done with the body and blood of the sacrifice. Lev. 1:1-17 spells out the selection, place, manner of death, and the disposition of entire sacrifice. Note verse five especially for the importance of the blood of the sacrifice, it is not spilled on the ground and soaked up by the dust, but collected for a specific and highly symbolic (of Christ's blood) use by the priest and for the people. See also Lev. 3:2 and 17:6. The first Passover inaugurated the keeping of and specific use of the blood of the sacrifice (Ex. 12:1-13). Verse seven leaves no doubt as to the necessity and use of the blood of the sacrifice: "And they shall take some of the blood and put it on the two door posts and on the lintel of the houses where they eat it." The very specific reason for the blood to be applied in the prescribed manner is seen in verse thirteen: "Now the blood shall be a sign for you in the houses where you are. And when I see the blood, I will Passover you..." [Have you ever had even a drop or two of your own blood drip to the ground? It turns the dry dirt into a gooey mess, and the blood disappears, and you are left with moist dirt with no evidence that it was your own blood in the dirt.] The blood of the animal was collected and used in the manner given in order for the Angel of death to pass them by. This is all highly symbolic of the sacrifice of the Lamb of God and an integral part of the Gospel of Jesus Christ. The importance of the specific collection and application of the Blood of Jesus Christ cannot be annulled, altered, or hijacked and the Gospel remain the Gospel. Going further, Len. 17:11 says: "For the life of the flesh is in the blood, and I have given it to you upon the altar to make atonement for your souls; for it is the blood that makes atonement for your soul." Note carefully the phrase "it is the blood that makes atonement for your soul" and not merely a death without the shedding of the life blood.
Jesus Christ is our High Priest (Psa. 110:4; Heb. 5:6 & 10) and as such has fulfilled His High Priestly duties to perfection. Note in Lev. 1:3 some of the requirements, a male (Jesus Christ was a Man), without blemish (He was without sin), He offered Himself as did those in Moses' day offer their animals in sacrifice, of His own free will (John 10:17 & 18). Perhaps the most important duty of the High Priest was to bring the blood of a sacrifice into the Holy of Holies once a year (Heb. 9:7). Note he went in alone and "not without blood." As High Priest, Christ did the same thing as He entered the heavenly tabernacle (not made with hands) as seen in Heb. 8:2 ("the true tabernacle which the Lord erected, and not man") and Heb. 9:11 "But Christ came as High Priest of the good things to come, with the greater and more perfect tabernacle not made with hands, that is not of this creation." [The Tabernacle in the wilderness, Solomon's temple and the rebuilt version were symbols of the heavenly Tabernacle "made without hands" and were not worthy of the High Priestly Person and Office of Christ.] Heb. 9;12 continues on to say that when Christ entered the Holy of Holies in the Heavenly Tabernacle it was "Not with the blood of goats and calves, but with His own blood He entered the Most Holy Place once for all, having obtained eternal redemption." In Heb. 9:24 we find "For Christ has not entered the Holy Place made with hands, which are copies of the true, but into heaven itself, now to appear in the presence of God for us."
Heb. 10:4 states "For it is not possible that the blood of bulls and goats could take away sins." They were symbols and foreshadows of the eternal work of Christ accomplished by His death and resurrection and not the vehicle by which our sins are forgiven/removed . These animal sacrifices prescribed by the Law were the true precursor, pointing to Christ and His sacrifice as seen in Heb. 9:22, "And according to the law almost all things are purified with blood, and without shedding of blood there is no remission." This clearly indicates that a death without the shedding of the blood of the sacrifice is not acceptable to the Lord and therefore no sins will be forgiven if no blood is shed. The beginning of this is seen in the unacceptable offering made by Cain in Gen. 4:3-8 which resulted in the first murder. Abel's offering of a sacrifice from his flock was "respected" by the Lord.
There are over forty references to the blood of Christ being the instrument of choice to save sinners. Not just His death (without blood shed), but specifically death with the shedding of His Life's blood. One of these is 1 John 1:7 "But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin." This is continuing action, all day, every day, never failing, "when I see the blood..." (Ex. 12:13). This is the explicit reason why the Lord Jesus brought with Him into the Holy of Holies in heaven His own blood---all of it. An interesting statement is made by the Lord recorded in Luke 24:39, "...Handle Me and see, for a spirit does not have flesh and bones as you see I have." No mention of His blood, since He had already delivered it to His Father in the heavenly tabernacle.
Col. 1:14 "In Whom we have redemption through His blood..."
Eph. 2:13 we have been "brought near by the blood of Christ"
Eph. 1:7 "In Whom we have redemption through His Blood"
Rom. 5:9 "...having now been justified by His blood"
Acts 20:28 "...which He purchased with His own blood"
1 Peter 1:18 &19 "knowing that you were not redeemed with corruptible things...but with the
precious blood of Christ"
Rev. 1:5 "...To Him who loved us and washed from our sins in His own blood"
Rev. 5:9 "...And have redeemed us to God by your blood..."
Rev. 12:11 "And they overcame him by the blood of the Lamb..."
What a great and wondrous thing the Lord has done: freely giving His Life, His blood, (Lev. 17:11)that we might live unto Him.
"Afresh, precious, precious Jesus, I resign this body to You, for doing or suffering, for living or dying. Will You accept it? Will You use me for Your glory more than heretofore, that You may have some little return for all the benefits You have done to me? Oh, do grant this request; my heart longs for it, my spirit pleads for it; and "if You will, You can." You know the hot temptation of which I am the subject. Bring Your glory out of it, and keep me from the evil, and it shall be well." - Ruth Bryan
