Commentators like Charles Spurgeon highlight a crucial distinction: the Israelites crossed the sea by faith, while the Egyptians drowned through presumption. Both groups attempted the same physical act, but Israel acted on God's specific promise. The Egyptians, lacking this divine word, acted with reckless courage, which led to their destruction. This shows that attempting what God has called others to do, without a personal call yourself, is not faith but dangerous presumption.
