In this sermon from Exodus 19, Matt Sikes explains Israel's arrival at Mount Sinai and their terrifying encounter with the holiness of God. Through thunder, lightning, fire, smoke, an earthquake, and the sound of a trumpet, God reveals that sinful people cannot casually enter His presence or approach Him on their own terms. The sermon presents three central truths: the call to covenant faithfulness, the inability of the people, and the necessity of a mediator. Although Israel confidently promises to obey everything God commands, they cannot fulfill the perfect demands of His law. Moses temporarily stands between God and the people, pointing us forward to Jesus Christ, the true and greater Mediator who perfectly fulfilled the law, bore its curse, and brings His people confidently into God's presence.
