Why should Christians prioritize unity in the church?

Unity in the church is paramount for Christians as it not only reflects the character of Christ but also serves to fulfill His mission. In John 17:21, Jesus prays for His followers, '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.' This prayer reveals that the unity of believers is a testimony to the world about the love and saving grace of Christ. When Christians cultivate relationships marked by love, humility, and mutual support, they exemplify the message of the Gospel and present a compelling witness to those outside the faith. Moreover, unity allows the church to function effectively as one body, accomplishing greater things together through the diverse gifts given to each member by the Holy Spirit.
