the church worships through Christ, with access to the Father, and in one Spirit (Eph. 2:18). It is the Spirit who binds us together in unity and peace despite our personal, ethnic, and social differences so that the church is one body of worshipers (1 Cor. 12:12–13; Eph. 4:3–4). The Spirit fills us with truth and joy so that we sing psalms, hymns, and spiritual songs to the Lord (Eph. 5:18–20). Therefore, the knowledge of the Spirit protects the simplicity, unity, and spirituality of worship. 6.
