The sermon on Romans 8:6–8 contrasts two mindsets: the mind set on the flesh (unregenerate people) leads to death and is actively hostile to God, refusing—and indeed unable—to submit to His law or please Him due to total depravity and total inability. In contrast, the mind set on the Spirit brings life and peace through the regenerating work of the Holy Spirit. The preacher stresses this hard, pride-crushing biblical truth, urging believers to proclaim it faithfully rather than softening it with man-centered views, and to examine their own spiritual condition while trusting God alone for transformation.
