How does Ephesians teach about Christ’s relationship to the church?

The book of Ephesians reveals that Christ is the head of the church, portraying His authority and role in the lives of believers. Ephesians 1 highlights that He is sovereign over all things, and the church is His body, which He loves and cherishes. As the head, Christ administers the spiritual life and governance of the church, ensuring that His people are guided and protected. This relationship is characterized by love, as Christ gave Himself for the church to purify and sanctify it, marking the depth of His commitment and affection for His people.
