How do we know the importance of peace among Christians?

The importance of peace among Christians is underscored in the sermon by highlighting that God, being a God of peace, calls His people to be peacemakers (Matthew 5:9). This principle is rooted in the nature of God Himself, as Christ, the Prince of Peace, exemplifies reconciliation. The church is to reflect this peace, showcasing love and unity, as instructed by Jesus when He said that all men will know they are His disciples by their love for one another (John 13:35). The failure to resolve conflicts biblically can damage the church's witness and negate the gospel's effectiveness in bearing witness to the world. Consequently, Christians are called to live in harmony, striving to resolve differences among themselves in a way that glorifies God.
