If anyone thinks that they have said a prayer that God hasn't heard from someone else at some time or another, they are deceived. It is all repetition for God. In fact, it is a little conceited to think that your very own prayer is more effective and efficacious than using God's inspired Scripture to pray. The Jews and later the Christians (Catholics) used the Psalms as prayers.
Our Father, who art in Heaven, hallowed be thy name, thy kingdom come, thy will be done on earth as in heaven. Give us this day our daily bread and forgive us our sins as we forgive those who sin against us. And lead us not into temptation but deliver us from evil, Amen.

Dearest Lowered, we jes wanna pry, we jes wanna let you kneew that wyee kneeow yore in Heaven, and we jes pry that yore naime be hollowed all across the werld lahk it is up there in heaven. And Lowered, we jes pray that you-ll feed us with the mailk of rahtchussnuss tadaiy, and have murcy own us, Lowered, we jes aisk that you-ll haive murcy own us and we jes promise, Lowered, to be compassionate to others.... blah blah blah.
Tell me, which one is prattling mindlessly (and endlessly)?
