Paul wrote to the Ephesians about the importance of unity. As there were people from diverse backgrounds in the Ephesus church, Paul taught that true unity can be achieved through Christ. This unity involves all aspects of life, including the church, its leaders, and relationships. God's ultimate plan is to bring all things under Christ's authority in heaven and earth. Through accepting our destiny in Christ, God gives us the Holy Spirit to guarantee this unity. We are called to maintain the unity of the Spirit through behaving respectfully, bearing with one another, and letting the Holy Spirit lead us in peace.
