S: The mind of sinful man is death but the mind controlled by the Spirit is Life & peace.
O: Paul is explaining to the Romans (and us) that there is a choice:: two opposites. To be controlled by thoughts of sin or by thoughts of the Spirit. For each of these there is a consequence, sin -> death & Spirit -> life & peace.
A: To me, peace is the critical word in this passage. Life and Death are eternal consequences, but peace is a worldly and obvious sign that I’m on the road to life.
P: Lord, give me strength and wisdom to choose to live controlled by the Spirit and let peace be the sign that I’m on the right track.
