How do we know that Jesus Christ is the Rock mentioned in Exodus?

The identification of Christ as the Rock is a crucial theological point that connects the Old Testament events to New Testament fulfillment. In 1 Corinthians 10:4, Paul clearly articulates that the rock which provided water to the Israelites during their exodus was, in fact, Christ. This declaration serves to illuminate the typology of the Old Testament, where physical sustenance foreshadows the spiritual sustenance found in Jesus. The smiting of the Rock by Moses reflects the justice of God being directed toward Christ during His crucifixion, consequently providing believers with the 'water of life' (John 4:14). Thus, understanding Christ as the Rock deepens the significance of both the historical event and the believer's spiritual journey.
