How does the imagery of the rock relate to Christ in salvation?

The rock typifies Christ not only as a protector but as the source of living water, crucial for spiritual life. In John 4:14, Jesus reveals that whoever drinks of the water He offers will never thirst again, presenting Himself as the fulfillment of the rock's spiritual significance. This metaphor underscores the providence of Christ as essential for salvation—a flowing source of grace and sustenance for struggling sinners. Each believer is invited to partake in this living water, reaffirming the central role of Christ in the Christian faith.
