Why is Christ called the rock in the Bible?

In Psalm 61:2, the imagery of God as a rock signifies His unchanging nature and strength, providing refuge for the weary and overwhelmed. The metaphor of rock extends into the New Testament, where Jesus states in Matthew 7:24, 'He that hears these sayings of mine and does them is like a wise man who built his house upon a rock.' This portrays Christ as the firm foundation for our faith. Believers find shelter in Christ, the rock of our salvation, ensuring that they are secure from any storms of life and judgment.
