Why is unity and peace important in the church according to the Bible?

The Scriptures highlight that the church is called to maintain unity and peace despite differing opinions on non-essential matters. Paul emphasizes this in Ephesians 4, stressing that God has called us to peace, and conflict often arises from fleshly desires rather than spiritual truths. In a healthy church, all members agree on core aspects of the gospel, fostering an environment where they can grow spiritually and share the message of Christ without hindrance. The presence of disagreement on essential matters indicates a fundamental issue with one's understanding or relationship with the Lord.
