Nearly 500 years ago Martin Luther served his barber providing him with a simple way to pray. A hand-written letter outlining how to pray using the Bible and the creeds. I seem to always need prayer to be simplified for me. Therefore, I always come back to Luther’s little pamphlet. Here is a link to the .pdf of it and an introductory quote.
I will tell you as best I can what I do personally when I pray. May our dear Lord grant to you and to everybody to do it better than I! Amen.
First, when I feel that I have become cool and joyless in prayer because of other tasks or thoughts (for the flesh and the devil always impede and obstruct prayer), I take my little psalter, hurry to my room, or, if it be the day and hour for it, to the church where a congregation is assembled and, as time permits, I say quietly to myself and word-for-word the Ten Commandments, the Creed, and, if I have time, some words of Christ or of Paul, or some psalms, just as a child might do.
It is a good thing to let prayer be the first business of the morning and the last at night. Guard yourself carefully against those false, deluding ideas which tell you, “Wait a little while. I will pray in an hour; first I must attend to this or that.” Such thoughts get you away from prayer into other affairs which so hold your attention and involve you that nothing comes of prayer for that day.
