What does 'having preeminence' mean in a church context?

In 3 John 1:9, John warns against Diotrephes, who loved to have preeminence among the brethren. This preeminence reflects a dangerous desire for power and authority that elevates oneself above God's divine order. Such behavior disrupts church unity and goes against the teachings of Christ, who exemplified servant leadership. Every believer, especially church leaders, must recognize that true authority comes from God, and any attempt to claim personal preeminence leads to chaos within the body of Christ. Faithfulness, humility, and submissiveness to God's will should define leadership in the church.
