How do we know that the relationship between Christ and His church is secure?

The security of the relationship between Christ and His church stems from the new covenant established by Christ Himself, symbolized in His relationship with His bride. Unlike the conditional covenants of the Old Testament that could be broken due to disobedience, the covenant of grace offers assurance that Christ will never divorce His bride. This is articulated through the metaphor of the beams of cedar and rafters of fir, which suggest a strong, enduring structure. The church, built upon Christ as the Rock, is promised that the gates of hell will not prevail against it, ensuring that believers are eternally secure in their salvation and relationship with Him.
