What is peace? The cross is the place where Jesus brought peace to the earth. Believers should have a foundational internal peace. Not having peace is a warning sign there are areas you need to work out with God. Jesus blessed the peacemakers. We should have enough internal peace that it brings external peace to other people. The devil markets a false peace,  a peace among people without God's Lordship. God's peace is not peace at all cost. It does not come from compromise; it comes from Godly conflict. Peace is a prince, the person of Jesus. When you speak His Name, it brings Peace.
