There is a beautiful hymn called "We are People of God's Peace". It's number 407 in the "Hymnal: A Worship Resource" , the Mennonite hymnal.
We are people of God’s peace as a new creation,
Love unites and strengthens us at this celebration.
Sons and daughters of the Lord, serving one another,
A new covenant of peace binds us all together.
We are children of God’s peace in this new creation,
Spreading joy and happiness, through God’s great salvation.
Hope we bring in spirit meek, in our daily living,
Peace with everyone we seek, good for evil giving.
We are servants of God’s peace, of the new creation,
Choosing peace, we faithfully serve with heart’s devotion.
Jesus Christ, the Prince of peace, confidence will give us.
Christ the Lord is our defence; Christ will never leave us.
