What does the Bible say about Jesus as the head of the church?

In Ephesians 1:22-23, Scripture clearly states that God has set Christ as the head over all things to the church, which is His body. This signifies His authority and sovereignty over the church, ensuring that He governs and sustains it in every aspect. Just as the head controls and directs the body, so does Christ direct and empower His church, fulfilling His purpose through it. The image of Christ as the head illustrates not only His leadership but also the intimate relationship between Christ and His people, as they are united in Him as members of one body.
