How does the story of the Israelites reflect God's grace?

In Exodus, the Israelites find themselves in a seemingly impossible situation, encamped by the Red Sea with Pharaoh's army pursuing them. God’s deliverance is a demonstration of grace; they did not earn or deserve their freedom from Egypt. Despite their complaints and lack of faith, God intervenes, showing that His mercy is not contingent upon their actions. This aligns with the theme of grace in the New Testament, where salvation is depicted as a gift bestowed upon undeserving sinners. Ephesians 2:8-9 highlights that by grace we are saved through faith, underscoring that it is God's work from beginning to end. The Israelites' experiences exemplify that salvation is wholly contingent on God's mercy and not on human merit.
