Loving God is not for God's benefit, for It can gain nothing from us. Loving It reflects back into our consciousness, thereby helping us become love-oriented.
Our free will is so sacrosanct that we are free to deny that we even have it, and free to be self-defeating fools living in the misery of our selfishness.
There is a better way, though. The choice is yours, my friend.
It is not uncomfortable once we realizing that we are but a mote, a talented mote in charge of the Earth, but a mote nonetheless. Once reaching humility, we are then free to bask in the glory of being a human being with the power to choose selfless love or selfish foolery, the power to learn and explore this magnificent universe full of wonder.
Reaching out to become love, we find peace in service, joy in our every interaction.
And, yes, via Castaneda's Don Juan, there is the known, the unknown, and the unknowable. The Creator of all that will ever exist is Unfathomable, Timeless, the Ultimate Loner, but we are capable of communing in some small extent with It, learning a tiny sliver of Its Nature.
The test is to connect with our Creator and ask for the proof you seek. It is why we are here, but we are free to choose to ignore our potential, because our free will is so freely given that we are free to choose ignorance over fulfilling humanity's highest purpose.
In the clarity of communing with love, our subjective reality is harmonized with the truth of existence, thus our knowing transcends thinking. It is our highest purpose, but like all great loves, it is freely given with no obligation, only responsibility for our choices and their effects upon others.
As Rumi said, "The Way goes in." I have described this process more fully in other comments.
Okay sure, faith is fine and I don't oppose people being religious, but it seems very strange to slot this stuff into a discussion about physics if it's not empirical.
Is there any empirical test for such things?
