The sermon centers on the necessity of understanding God's righteousness as the foundation for grasping both human sinfulness and the fullness of Christ's atonement, drawing primarily from Deuteronomy 4 and the Heidelberg Catechism Lord's Day 5. It emphasizes that God is a consuming fire—righteous, holy, and demanding full obedience, punishment for disobedience, and complete satisfaction for sin—revealing that no human can meet this standard due to inherent sinfulness and the infinite nature of divine justice. The sermon underscores the futility of self-salvation, contrasting human weakness with the divine requirement for a perfect, divine and human mediator, which Christ alone fulfills through substitutionary sacrifice. By reflecting on the historical and theological weight of God's justice, the sermon calls believers to abandon self-reliance, embrace the depth of their need, and cling to Christ as the only source of true satisfaction, mercy, and strength, ultimately motivating a life of gratitude and obedience rooted in the gospel's transformative power. 1.
