How does the encounter with the rock relate to the concept of grace?

The encounter with the rock illustrates God's immense grace and mercy, especially when considering the Israelites' entitled demands and lack of faith. Despite their rebellious attitude as they chided Moses, God faithfully provided water from the rock, showcasing His compassion toward the undeserving. This act of providing sustenance illustrates that God's grace is not dependent on our merit. Instead, it flows abundantly from His character and the accomplished work of Christ, who satisfies all the needs of His people by His grace alone.
