The sermon explores the ongoing struggle within the early church regarding adherence to the law, emphasizing that justification comes through faith in Christ, not through works. Drawing from Galatians, the preacher highlights the contrast between the Old Covenant and the New, asserting that zealous pursuit of legalistic practices ultimately undermines the transformative power of the Holy Spirit and the adoption as sons of God. The message serves as a pastoral plea for believers to remain steadfast in their faith, recognizing that true freedom and inheritance come through Christ alone, and warning against the dangers of reverting to a bondage of legalism and false teachings.
