I find it helpful to think in these terms. Our biography is written in two volumes. Volume one is the story of the old man, the old self, of me before my conversion. Volume two is the story of the new man, the new self, of me after I was made a new creation in Christ. Volume one of my biography ended with the judicial death of the old self. I was a sinner. I deserved to die. I did die. I received my deserts in my Substitute with whom I have become one. Volume two of my biography opened with my resurrection. My old life having finished, a new life to God has begun.
