Not the way I see in. Don't have to trust in anything. Just accept reality as it is presented to your awareness.
Distrusting everything, is no way to live life. You would live in constant fear and isolation if you lived with distrust in everything. Accepting reality can be done with trust and hope for goodness to carry you through. Or another way would be accepting life with a fatalistic resignation, than nothing matters and death is the only truth in life. That leads to apathy and a loss of anything good in life. It's a form of suicide.
As I tried to say, there is a balance between having faith and being accepting of life, and the other which is being fearful of life and either misusing faith to try to control it, or abandoning all hope and becoming fatalistic. Nihilism is not living. Neither is denialism through wishful thinking inappropriately mistaken by many as "faith",
which it is not.
Making the opposite argument doesn't prove any caring is involved in either case by the universe.
Life existing, love existing, happiness, joy, and connection existing, is proof of caring in the universe. That death also exists, is not proof that the universe is uncaring, cold, and impersonal. There is a balance to be had, and faith that accepts reality on its terms, both the good and the bad, is healthy. Nihilism or denialism is not. They are just flipsides of the same coin of fear.
Or one could not use the concept of God at all in their meta view of the universe.
To me any metaview really is a view of "God" by whatever other term you prefer. It basically means how one views Ultimate Reality, which includes everything from atoms to love, to thought, to life, to death, to every single aspect of experienced reality for us as human beings.
So anyone that considers the "big picture" in that way (not just physics), is using the "God concept" whether they call it by that word or not. That word simply means the "big picture" of All That Is. Some in considering that, might imagine it be a "guy in the sky", but that's hardly a very sophisticated understanding, and certainly not the limitations of it.
Love is a biochemical process of the brain.
Seriously? That's all love is to you? Tell that to your mother when she tells you she loves you, that that's all her love is. To say it's just chemical processes, well, that's sounds like reducing love down to the "warm fuzzies" that a 13 year old middle schooler calls "love" when they have a crush on someone. I'm talking adult ideas of love here. Not that.
No, it's a lot more than that of course. It's how we hold others in our hearts. Our attitudes towards them. Our philosophy towards life. It's a condition of our being. And so forth.
One can create whatever narrative around that they want, doesn't change the fact of what it is.
Wanna bet? How we perceive things, very much influences not only our experience of that thing, but the nature of the thing, or even the very thing itself. We interact with the world. We aren't just passive victims of it.
How we frame reality, quite literally creates that reality for us in no small way. Not 100% off course. But we certainly can and do influence the world around us. If you see the world as hateful and fearful, that is the reality you will create for yourself through that narrative. That is how reality works.
Sure, one can use romantic idealism in their consideration of the universe.
Still facts don't care about the myths we create to explain the universe to ourselves.
I think there are more balanced ways than either a fatalistic nihilism or a romantic idealism. This all or nothing view of reality is rather, non-reality.
Or let go of any need for faith and accept the reality of reality. But, baby steps I suppose.
Accept what version of reality? Which set of eyes version of reality? Can you tell me what you think that is?
