Romans 8:12-17 presents us with one of Christianity's most profound mysteries: the reality of God's Spirit actually living within us. This isn't just poetic language or metaphor—it's the defining characteristic that separates Christianity from every other religion. No follower of Buddha claims to have Buddha living inside them; no adherent of any other faith makes such a claim. Yet we who believe in Christ have received something extraordinary: somebody living in our somebody. This passage challenges us to ask a critical question: if the Holy Spirit lives in us, does He actually have us? We're presented with two masters—our old sin nature that leads to death, or the Spirit who leads to life. The sermon uses vivid imagery to illustrate this choice: we're like elephants who were chained as babies and now remain captive even though we have the strength to break free. The Spirit gives us that strength, that immune system against spiritual death. When we allow ourselves to be led by the Spirit, we're not just following better rules—we're following a better Leader who transforms us from the inside out. The practical application is clear: what we feed grows, and what we starve dies. Through the sword of the Spirit—God's Word—we have the power to put to death the misdeeds of the body and truly live.
