Peace should be a hallmark of the godly person, first because it is a Godlike trait: God is called the God of peace several times in the New Testament. He took the initiative to establish peace with rebellious men, and He is the author of both personal peace as well as peace among men. Peace should be part of our character also because God has promised us His peace, because He has commanded us to let peace rule in our lives and relationships, and because peace is a fruit of the Spirit and therefore an evidence of His working in our lives.
