Lord's Prayer can be said in one quarter of a minute, just fifteen seconds. Even for a large congregation of people to repeat it slowly takes only half a minute. Yet Jesus would spend half the night praying that same prayer. Very few ever learn to pray it. The power comes, not in the saying, but in the praying of the prayer.
Words merely form the frame on which the temple of thought is built.
The power of the Lord's Prayer is not in the words, but rather in the pattern of thinking in which our minds are formed. When our thoughts begin to flow in the channels of the Lord's Prayer our minds do become new, and we are transformed. I cannot say Our if I live in a watertight spiritual compartment. I cannot say Father if I do not demonstrate the relationship in daily living. I cannot say which art in heaven if I am so occupied with the earth that I am laying up no treasures there.
