But since, however few they may be, yet there are words which He Himself also is about to speak, by which He would teach us to pray; it may be asked why even these few words are necessary for Him who knows all things before they take place, and is acquainted, as has been said, with what is necessary for us before we ask Him? Here, in the first place, the answer is, that we ought to urge our case with God, in order to obtain what we wish, not by words, but by the ideas which we cherish in our mind, and by the direction of our thought, with pure love and sincere desire; but that our Lord has taught us the very ideas in words, that by committing them to memory we may recollect those ideas at the time we pray.
