How do we know that Jesus Christ is the cornerstone of our faith?

The cornerstone concept is firmly established in scripture where Peter quotes Isaiah, stating that God has laid a 'chief cornerstone' in Zion, which is Christ (1 Peter 2:6). He is described as elect and precious, fulfilling the role of the cornerstone that supports the entire structure of the Church. For believers, recognizing Jesus as this cornerstone is crucial for understanding our identity and purpose. Without Him, we lack the foundation necessary for true faith and spirituality. The church is built on the truth of His resurrection and the grace He offers, confirming the power of the Gospel for salvation.
