What does it mean to 'look to the rock' in Isaiah 51?

In Isaiah 51:1, God commands His people to 'look to the rock from which you were hewn.' This is a call to remember Abraham, the father of their faith, and by extension, the origins of their own salvation. Looking to the rock refers to understanding one’s spiritual lineage and acknowledging that it is God who called and chose us for salvation. It serves as a reminder of His faithfulness and the depth of His grace manifested in choosing the unlikely and redeeming them for His purpose, which is further articulated in Romans 9:11-16.
