How do we know that unity is essential for Christians?

Unity is central to the Christian faith because it encapsulates the teachings of Christ, who prayed for His followers to be one (John 17:21). This unity mirrors the relationship within the Trinity and is foundational for the church's witness to the world. It fosters love and mutual support, enabling Christians to grow together and testify to the gospel's transformative power in their lives. When believers dwell together in unity, it showcases the divine work entrusted to them, promoting peace and fostering community.
