Becoming a New Creation
As Christians, we are new creations. Our hearts of stone have been turned into hearts of flesh. In this metaphor, flesh is used as a positive figure, not a pejorative one. Where once my heart was cold and recalcitrant, dead and inert to the things of God, now it throbs and pulsates with spiritual life. Once I was biologically alive but spiritually dead. Now I am biologically alive and spiritually alive as well. I am a new person.
There is radical discontinuity between my new self and my old self. This radical discontinuity, however, is not total discontinuity. A link between the old man and the new man remains. The old man has been dealt a mortal blow. His total destruction is certain, but he is not yet dead.
The conflict of the Christian life is a struggle with sin. Sin no longer has dominion over us if we are in Christ, yet sin is still in us. Regeneration liberates us from the bondage of original sin, but our corrupt nature is not totally annihilated this side of heaven.
Paul speaks of the warfare that goes on between the flesh and the spirit. “For the flesh lusts against the Spirit, and the Spirit against the flesh; and these are contrary to one another, so that you do not do the things that you wish” (Gal. 5:17).
Thank God for the new heart of flesh He has implanted in your spiritual being.
