All commentators unanimously identify the 'stone' in this verse as a direct prophecy of Jesus Christ. God promises to build His church on a foundation that is 'tried' (tested and proven), 'precious,' and 'sure.' Scholars explain that Christ is this cornerstone, providing unshakable stability for God's kingdom and uniting all believers as one structure. This promise was a source of hope for ancient Israel and remains the bedrock of Christian faith.
