As Pastor David continues through the book of Romans, he will be exhorting us to examine our hearts to see whether the spirit of God dwells in us, or not. If the Spirit of Christ who raised Christ from the dead lives in you, then that same power can raise you out of your sinful life. It is this realization that we must understand in order to overcome sin. If you live according to the flesh, you will die; but, if you live according to the Spirit, you will live. Living in the flesh will bring you spiritual death.
