Sin = eternal death.
Jesus is the source of life. JESUS gave us life and can give life to a million more people.
Jesus is 100% God and the creator of mankind.
When Jesus died for our Sins because He was sinless and because He has life in and of Himself He was not able to be held in the realms of death. The life He has is so strong that death could not hold Him.
So Jesus did die for our sin and suffered the death of those saved, but the life He has in Himself was greater then all the death combined.
His death is a part of the great mystery of the gospel, for it is impossible for us to understand how the divine Son of God, the Creator, who had life in himself, could die. But as he, who knew no sin, took our sin upon himself,-was made to be sin for us, so he voluntarily became obedient unto that death which sin brings. He died for us, however, and not for himself; and since there was no stain of sin upon him, it was not possible that death should hold him (Acts 2:24), for it is sin alone that gives power to death. He had life enough for himself and for all the world besides; therefore when he laid down his life as a forfeit to the violated law, he could take it again.
