What does it mean that Christ is the cornerstone of salvation?

The metaphor of Christ as the cornerstone is vital for understanding the nature of salvation. A cornerstone is the first stone set in construction, establishing the position and stability for the entire structure. In Isaiah 28:16, God promises to lay a precious cornerstone in Zion. This points to Christ, who is the foundation of our faith. Without Him, our efforts are like a building without a solid base, destined to collapse. Believers are recognized as living stones, built upon Him, and this reinforces the truth that salvation comes from Him alone, offering hope and stability in a world of uncertainty.
