This sermon centers on Exodus 34, revealing God's character as merciful, gracious, and faithful, yet holy and just, through the renewal of His covenant with Israel after their idolatry with the golden calf. It unfolds four key aspects of God's covenantal relationship: mediation through Moses, who foreshadows Christ as the ultimate intercessor; revelation through God's written Word, which is divinely inspired and essential for knowing God's true nature; condescension, as God descends in glory to meet humanity, prefiguring Christ's incarnation; and the proclamation of God's personal name, Yahweh, which signifies His eternal, covenant-keeping identity and demands worship and honor. The sermon emphasizes that only through Christ—our true mediator, revelation, and the full embodiment of God's name—can sinners find forgiveness, reconciliation, and the assurance of God's presence. Ultimately, it calls listeners not merely to know about God, but to personally trust in Christ as Lord and Savior, responding in worship and faith.
