Summary: For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord. Romans 6:23
When Adam and Eve sinned the judgment was that their life would be taken from them, not by God but by sin. The moment they sinned, they died, for the wages of sin is death (Romans 6:23). To fix this problem, God himself killed an animal and covered them with the blood of that animal (Genesis 3:21). Hebrews 9:22 says, without shedding of blood there is no forgiveness. In Leviticus 17:11, God said; "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." In other words those covered by blood sacrifice would be set free from the consequences of sin.
All the blood sacrifices made in the old testament were a type of the coming great sacrifice of Jesus Christ. Every time that God required a sacrifice, he was looking into the future, in his mind, their sins were covered by the blood of Jesus Christ. He forgave their present sins by looking at the future sacrifice of his Son. The blood of Jesus paid for our past, present and future sins, Hallelujah.
Jesus is the redeemer of all ages, he was not there when Adam and Eve sinned, but his blood paid for them. This is why when he was hanging on that cross, and he shouted with a loud voice and gave up the ghost, there was an earthquake, and the tombs broke open, the bodies of the old testament saints came out of the graves. The blood of Jesus released them from the underworld prison, Satan had no choice but to let these ones go, for the blood of Jesus had set them free, Hallelujah. 1 Peter 3:19 says, Jesus preached to every spirit which was kept a prisoner in the underworld. Many years ago, Job looked at the sacrifice of Christ and shouted “I know that my redeemer liveth” (Job 19:25). This Jesus, ladies and gentlemen, is the only way, he is the only formula to God the Father. Blessed be God..............!
