In Exodus 3:13–4:9, Moses wrestles not only with Pharaoh’s opposition but with something much closer to home—his distrust of God’s people. Hurt by rejection forty years earlier, Moses now finds it harder to believe that Israel will listen to him than to believe that Pharaoh will eventually let them go. In revealing His name, ‘I AM,’ God shows Moses that true security is not found in self-protection or distrust, but in His unchanging character and faithful presence. This sermon explores how hurt can harden into distrust, how distrust can quietly replace trust in God, and how the ultimate revelation of the Great I Am in Jesus Christ frees us to trust again. Because God is our refuge, we do not have to guard our hearts with suspicion—we can entrust ourselves to the One who was wounded for us and never fails.
