Without Shedding of Blood There Is No Remission:
"And almost all things are by the law purged with blood; and without shedding of blood is no remission." (Hebrews 9:22).
Under Law Dispensation almost all things are purged with blood. The reason the writer says "almost" is because there were a few exceptions such as fire, water and incense were used for purification.
When we think of Blood from a biblical viewpoint we think of atonement, death, forgiveness, and remission, (Leviticus 17:10-14). It is the blood that makes the atonement for your soul, to shed blood something has to die, and forgiveness is to pardon or let go of the person who has done you wrong without demanding any payment for the debt owed. Also to cease holding the person guilty after they have acknowledged and repented of their sins. Remission is very similar to forgiveness, but remission takes away the sins (John 1:29; Hebrews 10:4).
Genesis 3:21 - First Shedding of Blood:
In Genesis Chapter 3, we have learned of the fall of mankind in the Garden of Eden, where the serpent converses with the woman and enticed her to partake of the tree in the middle of the garden. The woman told him that God commanded them not to eat or touch it or else they will die. But the serpent told her she would not die, God knew that the day they eat of the fruit from the tree in the midst of the Garden their eyes would be opened and they shall be as gods, knowing good and evil.
The woman was deceived by the serpent and saw that the tree was good for food and pleasant to the eyes, and also desire to make one wise. Therefore, she took some and ate it. She also gave some to her husband Adam (Genesis 3:6). Proceeding to Genesis 3:21 God made coats of skin and covered them. Due to their disobedience, they have sinned and the first shedding of blood was done by God who made garments of skin for Adam and his wife and clothed them.
The Children of Israel were bound in Egypt for approximately 400 years under the afflictions of King Pharoah, suffering in slavery hoping that the Lord God would deliver them from the Egyptian's bondage. God had revealed the future to Abraham in Genesis 15:13, that for sure his seed will be afflicted by the Egyptians for a period of 400 years, prior to the actual event and this was referring to the Children of Israel.
But in Exodus 12:40 "Now the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years." This verse includes Abraham and Issac also when Abraham had lived in Egypt.
While the Children of Israel were in Egypt, God spoke unto Moses and Aaron and gave them specific instructions on how to prepare and eat the Lamb or a Goat kid. Exodus 12:5 "Your lamb shall be without blemish, a male of the year: ye shall take it out the sheep, or from the goats. Exodus 12:7 "And they shall take of the blood, and strike it on the two side post and on the upper door post of the houses, wherein they shall eat it."
When God passes through Egypt that night to execute judgment the Children of Israel were safe because they obeyed God's instruction and strike the blood upon the two sides of the doorpost and also the upper side of the doorpost. Therefore, the animals served as blood coverage and protection to save their lives. The blood of the lamb or goat symbolizes the blood of Jesus Christ and what was to come in the near future according to God's promise.
The animal's blood was a substitute for their sanctification, so without the shedding of blood, there is no remission. This shows that the atonement was made for each household to free the children of Israel from captivity and bondage.
The Covenant and Restoration:
The Old Covenant that God made with Israel required concise obedience to the Law or else death also daily and yearly blood sacrifices were performed in order to atone for their sin.
The Old Covenant was mainly based on the works and a shadow of good things to come (Hebrews 10:1-4). Also, it was pointed toward the Messiah who would redeem His people once and for all.
Whereas the New Covenant promises us the fulfilment of God's perfect plan for mankind through Jesus Christ, but only to those whose hearts are surrendered to Jesus Christ, (Jeremiah 31:31:34).
Hebrews 9:15 "Therefore, he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgression committed under the first covenant.
Luke 22:20 "And likewise the cup after they had eaten, saying, "This cup that is poured out for you is the new covenant in my blood.
This was pointing to Christ fulfilling the scripture by His death, burial, and resurrection at Calvary. Also, His shed blood would make an atonement for us.
Leviticus 17:11 told us that "For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes the atonement for one's life."
The blood of Animals was temporary atonement but the blood of Jesus Christ prevails forever and forever, it is eternal.
Conclusion:
God created us as perfect beings, but due to the serpent's deception in the Garden of Eden, causes a gap between man and God. But the perfect blood of (the second Adam) Jesus Christ restored us. This only applies to those in Christ who believe and accept Christ as their personal Saviour and Lord.
The blood represents life and this is why Jesus Christ died for us. Offering up His life and blood to redeem us from death, also the awesome Promise of Eternal Life (1 Corinthians 15:49-58).
Exodus 12:11-13, These verses are powerful revelations showing us how the Children of Israel obeyed what God had commanded them to do and by doing this they were fully covered from the wrath of God upon Egypt.
Moreover, we who are covered under the Blood of Jesus Christ, then if we obey God's moral commands and principles we also are covered and secured in the arms of God.
It is Jesus' blood that makes the difference because without shedding of blood there is no remission.
