Why is the concept of Jesus being the smitten rock important for Christians?

The concept of Jesus as the smitten rock is crucial because it encapsulates the core of the Christian faith—salvation through Christ's atoning sacrifice. As the rock was struck to provide water for the Israelites, so Christ was crucified to provide the living water of eternal life. This symbolism underlines that without Christ's sacrificial death, there could be no spiritual sustenance for believers. It serves as a reminder of God's provision and grace in Christ, emphasizing that true life is found in Him alone, an essential message that sustains the faith of every believer.
