What does the Bible say about Christ as the Covenant Head?

According to Scripture, Christ serves as the federal Head of the elect, which means He represents all believers in the covenant of grace. Ephesians 1:22-23 emphasizes that Christ is the Head of the Church, the body comprised of the elect, and He exercises His headship in various senses—providing spiritual life, guidance, and protection to His people. Just as Adam represented humanity, so Christ represents the elect, being chosen as their Head before the foundation of the world (Ephesians 1:4). This foundational truth illustrates the depth of the relationship believers have with Christ, affirming that all blessings and promises are secured in Him who represents them before God.
