Generally understood, the atonement is a reparation for an offense, wrong, or injury that brings reconciliation between two parties. It establishes a right relationship between the offended one and the offender.
In Christianity, we believe that we have sinned against God thus offending Him. The only satisfaction for His just wrath as He required was a perfect, sinless, and voluntary sacrifice and the shedding of blood.
Because we could not satisfy His wrath ourselves, Jesus did so.
Lev. 17:11-12 warned the Israelites about the importance of the blood in God’s eyes: “For the life of the flesh is in the blood, and I have given it for you on the altar to make atonement for your souls, for it is the blood that makes atonement by the life. Therefore I have said to the people of Israel, No person among you shall eat blood, neither shall any stranger who sojourns among you eat blood.“**
For this reason, Christ’s blood was shed at Calvary as the perfect Lamb that was slain (with no broken bones) to atone for our sins according to John 19:33-37:
“But when they came to Jesus and saw that he was already dead, they did not break his legs. But one of the soldiers pierced his side with a spear, and at once there came out blood and water. He who saw it has borne witness— his testimony is true, and he knows that he is telling the truth— that you also may believe. For these things took place that the Scripture might be fulfilled: “Not one of his bones will be broken.” And again another Scripture says, “They will look on him whom they have pierced.”
Isn’t God good to us? He provided His blood to forgive us from our sins! Amazing love, how can it be? What an amazing truth we can tell our counselees so that they can trust in Christ for the atonement of their sins, too!
