This sermon presents a profound theological reflection on the redemptive work of Jesus Christ, centering on two pivotal aspects: His propitiation and His purchase of salvation. It emphasizes that Christ's sacrifice on the cross was not merely a moral example or a symbolic gesture, but a divine act that fully satisfied God's righteous wrath by turning it away through His perfect obedience and sinless offering, thereby appeasing God's justice and restoring the relationship broken by human sin. The sermon underscores that Christ's work is not limited to forgiveness but includes the purchase of reconciliation—reestablishing a living, intimate relationship with God—and the eternal inheritance of everlasting life, secured by His blood and guaranteed for all who believe across every age. Drawing from key passages such as Romans 3, Colossians 1, and Hebrews 9, it affirms the timeless sufficiency of Christ's atonement, demonstrating that Old Testament saints were saved by faith in the coming Messiah, just as believers today are saved by faith in His finished work, making Christ the one and only mediator between God and humanity throughout history. The message calls both believers and unbelievers to a deep reverence for Christ, urging a life of continual meditation, worship, and proclamation of His saving work.
