How do we know Jesus is the 'rock' mentioned in the Bible?

In Psalm 18:2, David proclaims, 'The Lord is my rock, and my fortress, and my deliverer.' This metaphor for Christ is affirmed throughout scripture, including in 1 Corinthians 10:4, where Paul states that the Israelites drank from the spiritual rock, 'and that rock was Christ.' This assertion emphasizes that Christ is both our strong foundation and our means of salvation. Understanding Jesus as our rock reveals His unchanging nature and the reliability of His promises, serving as a source of hope and strength for believers.
