How do we know Christ is the fulfillment of the smitten rock?

We can know that Christ is the fulfillment of the smitten rock through the interpretation provided in the New Testament. In 1 Corinthians 10:4, Paul makes it explicit, stating that 'the rock was Christ.' This aligns with the prophetic foreshadowing present in the Old Testament, where the smiting of the rock anticipates Christ’s atoning work on the cross. Moreover, in John 4:10, Jesus offers water that leads to eternal life, establishing Himself as the ultimate source of spiritual sustenance and fulfillment. Our understanding is rooted in the exegesis of both Testaments, revealing the continuity of God’s redemptive plan that is perfectly fulfilled in Jesus Christ.
