"A lesson about how our union with Christ frees us from sin's dominion and empowers us to live a new life of obedience by the grace of God." The sermon, drawn from Galatians 2:17–21, powerfully defends the gospel of justification by faith alone against the charge that it promotes sinfulness, clarifying that true freedom in Christ is not license to sin but liberation from the law's condemnation and the power of sin. It emphasizes that believers are united with Christ in His death and resurrection, resulting in a new nature that hates sin and delights in God's will, making holy living not a legalistic obligation but the natural outflow of faith and love. The passage dismantles the misconception that grace encourages lawlessness, showing instead that grace both forgives sin's penalty and destroys its dominion through the transformative power of union with Christ, who now lives in the believer. The sermon concludes with a solemn warning: to add works to faith is to nullify Christ's sacrifice, making His death unnecessary and blaspheming the Gospel, and thus calls all to live not under fear of the law, but in joyful, loving obedience to the One who died for them.
