This week's Bible Lesson includes the Lord's Prayer and its spiritual interpretation found in Science and Health. There is a letter Mrs. Eddy wrote to an unknown recipient with instructions to pray the Lord's Prayer each day. Here is the letter.
Concord, N.H., Aug. 27, 1896
My precious child
May God abundantly reward your obedience and answer Mother's daily prayer. And He will. Love must will bless all unselfish endeavors to work for the cause of Truth. Be of good heart, you have everything for you and nothing against you. Every day pray the Lord's Prayer in the meaning and spirit thereof.
Thy Kingdom is come. Here ask for the true sense of God and man to come to your understanding and into your affections. Ask for just what you need spiritually. Ask to be made patient and loving when persecuted, to be strictly honest speaking the truth, and never misrepresented in even the smallest thing. Ask to be gently tempered and delivered from all anger or spirit of revenge. Ask for this daily bread to feed you. Under forgive my debts "as I forgive my debtors" (ask to love your enemies and to forgive them) even as you need God's dear pardon and deliverance from condemnation and punishment. Under "Lead me not into temptation, etc."(Pray for deliverance from yielding to the influence of mortal mind) either your own of another's and the recognition of but one Mind. Keep steadfast to this prayer and thought. Ask to know just how to do good and act wisely in your field of labor and that no sin or sinner can turn you aside from the right way or tempt you to stray. (Oh Mother is so alone on earth, has none to make the hours seem less long or cheer her labors. Oh yes, forgive me. She has all in God)
Here is what I found in V.C. Bath's book The Lord's Prayer in Daily Life.
This is the only petition that has any condition attached to it. It means that only just in accordance as we are doing to others can we expect to be done by; just as much as we are loving others can we expect to be loved; just as much as we are just can we expect to have justice around us. We must watch and look to ourselves and see how much we are loving, in fact, how much we are radiating good; so that we may be entitled to have love and joy around us, and may have the right, according to our prayer, to expect them in our homes and lives.
