How do we know that seeking peace with others is important in Christianity?

The importance of seeking peace with one another is underscored by the teachings of Jesus and the apostles. For instance, in Ephesians 2:14, Christ Himself is described as our peace, having broken down the walls of division. Furthermore, the Apostle Paul points out in 1 Corinthians 7:15 that God has called us to peace, which echoes the overarching message of the gospel. By promoting peace, we foster unity within the body of Christ, enabling us to support one another in our Christian walk and witness to the world of God's grace.
