This sermon on Exodus 4:1–17, examines Moses’ escalating objections to God’s commission and reveals that beneath them lies the common sin of unbelief. Despite witnessing God’s revelation at the burning bush and hearing His promises, Moses doubts Israel will believe him and then protests his own inadequacy, ultimately asking God to send someone else. In response, God patiently demonstrates His sovereign power through three symbolic signs that declare His authority over Pharaoh, Egypt’s false gods, sickness, and judgment, reminding Moses who He is and what He has promised to do. Even when God’s anger is kindled, His mercy prevails as He provides Aaron and continues His saving plan. The sermon concludes by showing that Moses’ weakness ensures that Israel’s deliverance will clearly be God’s work alone and calls believers today to ground their obedience not in self-confidence but in remembering who God is, trusting His gospel promises, and depending entirely on His grace.
