Why is Jesus called the rock in Christian theology?

The designation of Jesus as the rock in Christian theology conveys His steadfastness and the security found in Him. As outlined in Matthew 7:24-27, Jesus' teachings liken wise builders to those who construct their lives on the rock, which represents His word and truth. This concept is further emphasized in biblical passages such as 1 Corinthians 10:4, where Paul identifies Christ as the spiritual rock that provides sustenance and life to believers. Therefore, trusting in Christ as our rock guarantees that we stand firm against life's trials and the coming judgment, for He is the One who upholds and sustains us.
