In the old testament times, to purge a man from his sins the blood of animals was used. The life in the blood saved the man from his sins.
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 atonement for one’s life- Le. 17:11.
Day after day every priest stands and performs his religious duties; again and again he offers the same sacrifices- He. 10:11.
However, God wasn’t pleased with them.
“Sacrifices and offerings, burnt offerings and sin offerings you did not desire, nor were you pleased with them” - He. 10:8.
He sets aside the first {covenant} to establish the second - He. 10-9.
Then God was determined to purge Gentiles as well as Jews, so he sent his son like a lamb into the world.
“Look, the Lamb of God, who takes away the sin of the world! - Jn. 1:29.
For God so loved the world that he gave his one and only Son, that whoever believes in him
shall not perish but have eternal life- Jn. 3:16.
Jesus came into the world on a mission to save both Gentiles and Jews, who were under the yoke of sin, so that they will be set free.
In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace- Ep. 1:7.
The Son of Man did not come to be served, but to serve, and to give his life as a ransom for many- Mt. 20:28.
At first Jews didn’t believe in Jesus Christ. They claimed that they are not slaves of anyone.
They answered him, “We are Abraham’s descendants and have never been slaves of anyone. How can you say that we shall be set free?” Jesus replied, “I tell you the truth, everyone who sins is a slave to sin. Now a slave has no permanent place in the family, but a son belongs to it for ever. So if the Son sets you free, you will be free indeed- Jn. 8:33-36.
Let God be true, and every man a liar. As it is written: “So that you may be proved right when you speak and prevail when you judge - Ro. 3:4.
Jews crucified Jesus on the charge of blasphemy. As a result, the prophecies fulfilled.
He was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was upon him, and by his wounds we are healed. We all, like sheep, have gone astray, each of us has turned to his own way; and the LORD has laid on him the iniquity of us all. He was oppressed and afflicted, yet he did not open his mouth; he was led like a lamb to the slaughter, and as a sheep before her shearers is silent, so he did not open his mouth- Is. 53:5-7.
Just as Moses lifted up the snake in the desert, so the Son of Man must be lifted up,that everyone who believes in him may have eternal life- Jn. 3:14-15.
Jesus said, “It is finished.” With that, he bowed his head and gave up his spirit- Jn. 19:30.
Christ, our Passover lamb, has been sacrificed- 1Co. 5:7.
When you were dead in your sins and in the uncircumcision of your sinful nature, God made you alive with Christ. He forgave us all our sins,having cancelled the written code, with its regulations, that was against us and that stood opposed to us; he took it away, nailing it to the cross- Col. 2:13-14.
With his sacrifice our status has changed.
You are not your own; you were bought at a price - 1Co. 6:20.
So you are no longer a slave, but a son; and since you are a son, God has made you also an heir- Ga. 4:7.
This is the greatest power of Jesus’ blood. In addition to purging us, the blood has made us heirs to God.
Since we have now been justified by his blood, how much more shall we be saved from God’s wrath through him! - Ro. 5:9.
