When it comes to the pastor's prayer life, I note that there is something of a revival of the daily office among Lutheran pastors. I prefer to follow Luther's advice and keep it simple; "...pastors are now released from the useless and burdensome babbling of the seven canonical hours of prayer. I wish that, instead of these, they would read each morning, noon, and evening only a page or two in the catechism, the prayer book, the New Testament, or something else in the Bible. They should pray the Lord’s Prayer for themselves and their parishioners.
Martin Luther, Preface to the Large Catechism, from Concordia: A Reader's Edition (Concordia Publishing House)
Cf. Sasse, "I am a simple Lutheran who prays the catechism every day."
