The resurrection is all about life, life from the dead. And the most obvious thing about life is how mysterious it is, not to mention how holy it is.
The Puritan George Swinnock observed that Adam’s body was made out of the dust of the ground, while his soul was the direct result of the breath of God. This is why caring for the body is good, but soul-work is crucial. The Spirit of God is the Spirit of life. The Lord Jesus, after His crucifixion, was returned to the same ground that the first Adam was taken from. Our Lord was laid in a grave. But, as Scripture teaches, the Holy Spirit of God, the breath of God, raised Him from the dead.
“But if the Spirit of him that raised up Jesus from the dead dwell in you, he that raised up Christ from the dead shall also quicken your mortal bodies by his Spirit that dwelleth in you” (Rom. 8:11).
When we confess our sins and ask God not to remember them, we are asking, from the vantage point of our new life, that the times of our death be forgotten, and that any ongoing vestiges of that death be put away. And that is precisely what God is intending through the gospel. He intends for the contagion of everlasting life to work through the entire world.
This is why soul-work is so important. The contagion of this life is spread by the Spirit, and because He is the Holy Spirit, all that He breathes on and into is made holy.
