    Quick Answer

    Unity among believers is a command, not a suggestion — Jesus prayed for it, and Paul urged it as essential to the body of Christ.

    "That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me." — John 17:21 (KJV)

    The Biblical Answer

    Jesus prayed in John 17:21, 'That they all may be one; as thou, Father, art in me, and I in thee, that they also may be one in us: that the world may believe that thou hast sent me.' Unity is a witness to the world. Ephesians 4:3 urges believers to be 'endeavouring to keep the unity of the Spirit in the bond of peace.' Paul lists the basis: 'one body, and one Spirit... one Lord, one faith, one baptism, One God and Father of all' (Ephesians 4:4-6). 1 Corinthians 12 teaches that diverse members form one body. Psalm 133:1 celebrates, 'How good and how pleasant it is for brethren to dwell together in unity!' Unity doesn't mean uniformity — believers differ in gifts, perspectives, and practices. But they unite around essential gospel truths, love for one another (John 13:35), and submission to Christ as Head of the Church.
