Neat poem on the Lord's Prayer

I read about this poem by an unknown author in John MacArthur's book on prayer "Alone with God" and found it thought-provoking:
I cannot say “our” if I live only for myself in a spiritual, water-tight compartment.
I cannot say “Father” if I do not endeavor each day to act like His child.
I cannot say “who art in heaven” if I am laying up no treasure there.
I cannot say “hallowed be Thy name” if I am not striving for holiness.
I cannot say “Thy kingdom come” if I am not doing all in my power to hasten that wonderful day.
I cannot say “Thy will be done” if I am disobedient to His Word.
I cannot say “on earth as it is in heaven” if I will not serve Him here and now.
I cannot say “give us…our daily bread” if I am dishonest or an “under-the-counter” shopper.
I cannot say “forgive us our debts” if I harbor a grudge against anyone.
I cannot say “lead us not into temptation” if I deliberately place myself in its path.
I cannot say “deliver us from evil” if I do not put on the whole armor of God.
I cannot say “Thine is the kingdom” if I do not give to the King the loyalty due Him as a faithful subject.
I cannot say “the power” if I fear what men may do.
I cannot say “the glory” if I am seeking honor only for myself.
I cannot say “forever” if the horizon of my life is bounded completely by the things of time.
