It is through the willing death of this sinless One and His subsequent burial and resurrection that we can be relieved of our sins and their consequences. We now have a choice of whether to be in bondage to sin or live a changed life as a servant of our Lord and Savior Jesus Christ. Jesus' cruel death was a substitutionary death for us. Sin demands death. God told Adam and Eve they would die if they ate of the tree.
Death still remains as the consequence of sin.
However, by our accepting the supreme sacrifice of Jesus on the cross as being for our sins, we can receive remission of sins. Without shedding of blood is no remission. Our blood does not have to be shed and we don't have to die because Jesus' sinless blood and death was efficacious for all of our sins. If man will repent of his sins, his sins will be forgiven and can be remitted by the blood of Jesus Christ. In fact, it is for this purpose that Jesus Christ, God manifested in flesh, came into this world and died on the cruel cross of Calvary.
