Why is it important for Christians to remain united as a church?

The unity of believers is crucial for the health and function of the church, reflecting the love of Christ. When Christians come together as one body, it fosters an environment where the gospel can flourish and where mutual support can thrive. John 13:35 emphasizes this when it states, 'By this shall all men know that ye are my disciples, if ye have love one to another.' A united church not only encourages individual growth but also displays to the world the transforming power of the gospel. Just like the various members of a body work together (1 Corinthians 12:12-27), the church must support one another in sincerity and love.
