99% of the value of this Sacred, all sufficient prayer is in these 4 words. Everything else can come with these four. In fact, 98% of the value is in the first TWO words.
The degree to which we Imagine, and Live in every respect out of the Idea / Truth / Wisdom / Humanity / Totality that there is One Father of us All - Heaven will happen.
Often, usually, when I say this prayer, I don't make it past these first two words. I can get stuck in Imagining the implications for me of One Father of us all, making us all one family - for many, many productive minutes. And, for those times I make it no further than these first two words I'm ok.
These first two words put me close to, or in His Will. And that's all there is. The entire reason that Jesus lived and died for us was to knit us together as One Family with One Father. Heaven for the individual and the collective is inescapable in exact proportion to the degree to which this exists at any moment - for the individual, for the collective.
Father, what do you want me to do? Where in your family are you looking? What do you want me, with my strenghts, weaknesses and other particular circumstances to DO? NOW? This is the whole deal.
However, words 3 & 4 are enormously productive as well. "in Heaven" takes me to the world of spirit, and to the fact that in Truth, as I experience it in my moments of Wisdom, I/we are spirit beings - not Flesh beings. Who cannot imagine themselves transplanted into a robot entity and still being themself? Who can imagine their brain being removed, their Flesh kept alive, and still being themself?
Jesus invites us to NOT make this "world" our home, but to travel with Him, to follow Him to our Father's Kingdom in Heaven - NOW.
