Hebrews 9:22 NKJV
And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.
It all started in the Garden of Eden, where Adam and Eve were placed. At the very moment Adam disobeyed God, that was the very moment he discovered he was naked (So when the woman saw that the tree was good for food, that it was pleasant to the eyes, and a tree desirable to make one wise, she took of its fruit and ate. She also gave to her husband with her, and he ate. Then the eyes of both of them were opened, and they knew that they were naked; and they sewed fig leaves together and made themselves coverings. Genesis 3:6-7 NKJV). Sin has a way of bringing shame to the sinner, and in the case of Adam and Eve, the shame came from their nakedness. The only way Adam could think of, was to get some leaves to cover the the shame of nakedness.
That very day, the blood of an animal was shed, just because of the sin of Adam and Eve. Genesis 3:21 says "Also for Adam and his wife the Lord God made tunics of skin and cloth them". Let us analyze this; "where is the skin from? From an animal. Can you get the skin form an animal without killing it? I don't think so. Therefore, because of the shame of skin, the blood of an animal was shed to cover the nakedness brought about by sin".
From the fall of man, the only way people make atonement for their sin was by killing animals on behalf of the sinners (without shedding of blood, there is no remission HEB 9:22. Read the book of Leviticus Chapter 16). Out of love for mankind, God sent His only begotten Son (JESUS CHRIST) to come be the Ultimate sacrifice and pay the greatest price of atonement, so that we can be drawn to God again. He shed His blood at Calvary so that we will not need to shed the blood of any other animal before we can be connected to God.
As we celebrate Easter, we need to remember the price paid on our behalf, we need to remember the agony of Christ before the price was paid, we need to imagine what God went through before Christ ultimate price was made, (please read; THE AGONY OF THE ULTIMATE PRICE ). We need to remind ourselves that we need to love God and give our Lives to Him because He loves us by sending Jesus to die for our sins. Without shedding of blood, there is no remission, Christ shed His blood for our remission and we are FREE for ever.
GOD BLESS YOU.
