How do we know that Jesus is the chief cornerstone?

The assertion that Jesus is the chief cornerstone is rooted in Scripture. Ephesians 2:20 declares that the church is built upon Jesus as the chief cornerstone, which connects His person and work to the foundational truths of Christianity. Moreover, Mark 12:10 echoes this sentiment, describing how the stone rejected by the builders has become the cornerstone. This rejection illustrates the world's disbelief in Christ, but God’s appointment of Him as the cornerstone signifies His ultimate authority and power in the salvation message. By recognizing scripture’s consistent testimony about Jesus from both the Old and New Testaments, we affirm His centrality and primacy in the faith community.
