How do we know Jesus Christ is the rock mentioned in the Psalms?

The identification of Christ as the rock is firmly established in the New Testament. In 1 Corinthians 10:4, Paul declares that the rock which accompanied the Israelites was Christ. This connection between the Old Testament imagery and its fulfillment in Jesus illustrates the continuity of Scripture and highlights His role as the foundation of the Church. Furthermore, in Matthew 16:18, Jesus affirms Peter's confession of Him as the Christ, revealing that upon this rock, He will build His Church, ensuring that the gates of hell shall not prevail against it. This emphasizes the theological understanding that Christ is indeed the rock of strength and salvation.
