The promise of the Gospel is, as Lewis said, that death itself begins to work backwards. Death to the man who dies in rebellion is the end of everything good, for with his final breath all hope flees and the night looms eternal; death to the regenerate man is simply the end of sin, both in the giving and the receiving. Sin, and nothing more.
The real living follows the dying.
For this He died: that you, my friend, might truly live.
