Gracious and gentle and condescending God, God of peace, Father of mercy, God of all comfort; see, I lament before you the evil of my heart; I acknowledge that I am too much disposed to anger, jealousy, and revenge, to ambition and pride, which often give rise to discord and bitter feelings between me and others. Too often in this way I have offended and grieved you, my long-suffering Father, as well as my neighbors. Oh! forgive me this sin, and allow me to share in the blessings which you have promised to the peacemakers, who shall be called the children of God.
Amen.

Johann Arndt (1555 – 1621)
