God calls Moses to proclaim deliverance, yet meets his doubt with patient provision, giving signs, a spokesman, and a clear summons to obedience. The signs He performs reveal His power over all, foreshadowing the coming plagues and declaring that He alone blesses, judges, and saves. God also makes clear His sovereign rule, even over Pharaoh’s heart, while calling Israel His firstborn son and demanding their release. Through the sobering scene of blood and covenant, ultimately pointing to Christ, we see that deliverance comes by God’s provision of a substitute, where He gives His own Son so that His people might be spared and brought to worship.
