For the life of the flesh is in the blood, and I have given it to you on the altar to make atonement for your souls; for it is the blood by reason of the life that makes atonement.
Hebrews 9: 22
And according to the Law ... all things are cleansed with blood, and without shedding of blood there is no forgiveness.
Genesis 9: 3-6
Every moving thing that lives shall be meat for you; even as the green plant have I given you all things. But flesh with the life thereof, which is the blood thereof, you shall not eat. And surely your blood of your lives will I require; whether of a beast or of a man I will require it; and at the hand of every man's brother will I require the life of man. Whoso sheds man's blood, by man shall his blood be shed; for in the image of God made He man.
Blood represents the life of the creature. It's life is in its blood. That's why blood tests reveal what is going on in the health of one examined by medical people.
And whether man or beast kills a person, the killer must pay with his own life, because man is made in God's image.
God gave the blood of the beast on the altar to make restitution to God for sins. This demonstrates that we all deserve to die, since a life must be paid in substitution for our life, for our sins to be forgiven and covered by the animal's blood (see Leviticus chapter 1).
Jesus has now come to be the Lamb of God to shed His Blood on His altar, the Cross, which does more than just cover the sins that are there. The precious Blood He shed is God's own Blood, with endless power to actually wash away all our sins and cleanse us of every stain.
So when someone realizes that he deserves death, and lets Jesus take his death on the Cross, that is trusting Him to be Savior. Just to ask Him to save you won't make you a Christian; you must repent and believe. Turn around your thinking, and depend on Jesus to be your personal Sacrifice to die for you. Then God will be able to forgive you and make you His child.
Then God raised Jesus from the dead, and He was alive again, with a new life, that could go through locked doors. This Resurrection proved that God accepted His sacrifice. It also proves that Jesus is Who He said He was, God's own Son, and the Lord God of the Old Testament.
So put Your faith, your trust, in Jesus as your Savior, your personal Sacrifice. He will take away your sins and you will receive that new life, that Resurrection life, in the Person of the Holy Spirit Who will live in your spirit, making it alive and able to communicate with God.
And you will be one of His sheep, that He will call by name to go out, and be with Him forever.
Even so, come, Lord Jesus!
