What does the Bible say about unity in the body of Christ?

Unity in the body of Christ is a central theme in the New Testament, particularly articulated in Ephesians 4:3, where Paul urges believers to endeavor to keep the unity of the Spirit in the bond of peace. This unity is underpinned by the grace of God, which we all share in Christ. Believers are called to work together as one body, nurtured by the Holy Spirit, demonstrating humility, gentleness, and patience with one another. In doing so, we manifest the love of Christ and promote the health and growth of the Church as His body, highlighting the interconnectedness and mutual dependency of all its members.
