How do we know Christ is the living stone?

Peter refers to Jesus as the 'living stone' in 1 Peter 2:4-5, emphasizing that He is not merely a historical figure but the source of spiritual life for believers. He is the very foundation of the church, as affirmed by Paul in 1 Corinthians 3:11, stating that no other foundation can be laid than that which is Jesus Christ. This living stone symbolizes Jesus' active presence and sustaining power in the lives of His followers, as He provides spiritual life and enables them to be living stones themselves, contributing to a spiritual house dedicated to God.
