How do we know Jesus is the true foundation?

The Scriptures consistently affirm Christ as the foundation. For instance, in Ephesians 1:4, it states that He chose us in Him before the foundation of the world, indicating a divine plan centered on Christ. This foundation is described in Isaiah 28:16 as a 'precious cornerstone,' revealing the strength and reliability of what God has established. Jesus acknowledges this truth in Matthew 16:18, declaring, 'Upon this rock, I will build my church.' Hence, our assurance lies not only in His character but in the prophetic and apostolic testimony that affirms His role as the solid foundation for eternal security.
