When the disciples asked Jesus to teach them to pray, the Lord did not tell them to use their imaginations and express their feelings. He did not tell them that it really did not matter how they prayed, as long as they were sincere. And he certainly did not tell them to talk to God in their own words. . .the Lord's Prayer is at the heart of Christian prayer. All other prayers of the Church exist in relation to this prayer given by the Master Himself. They are either abbreviations or elaborations of it. They are in harmony with it, and cannot contradict it in any way.
