The sermon explores the apparent contradiction between Romans 6 and 7, clarifying that while believers are saved and freed from sin, the struggle with sin remains due to the lingering influence of the flesh. It emphasizes the importance of setting affections on things above, mortifying sinful desires, and actively pursuing righteousness through Bible study and a renewed mind, ultimately highlighting that a victorious Christian life involves a constant, intentional pursuit of God's will and a commitment to influencing others for Christ.
