What does the Bible say about Christ being our head?

In Ephesians 4:15, Paul emphasizes that Christ is the head of the church, which signifies His authority and leadership over all believers. This headship implies that Christ is not only sovereign over all creation but specifically over the church, His mystical body. As the ultimate authority, He governs the church’s actions and beliefs and provides sustenance and growth through His divine presence. This relationship reflects the intimate communion between Christ and His people, making Him both the ruler and caretaker of the church.
