O Lord, Teach Us to Pray, and Pray Well

In 1519 Martin Luther wrote a "Personal Prayer Book" to help people know how to pray in the midst of so much confusion about what true prayer is. In giving an example of how to pray according to the third petition of the Lord's Prayer, Luther writes this as part of his model for this petition:

Grant us true obedience, a perfect, calm, single-minded composure in all things—spiritual, earthly, temporal, and eternal. Protect us from the horrible vice of character assassination, slander, backbiting, frivolously judging or condemning others, and misrepresenting what others have said. O hold far from us the plague and tragedy which such speed can cause; rather, whenever we see or hear anything in others that seems wrong or displeasing to us, teach us to keep quiet, not to publicize it, and to pour out our complaints to you alone and to commit all to your will. And let us sincerely forgive all who wrong us and be sympathetic toward them.
