I understand struggling with the faith-vs-my-eyes thing. But... this is not one of those areas that conflicts with the gospel or with the creation story. And, the heliocentric model, if anything, proves that God is far, far greater than one who'd create an earth-centric universe, with a flat world as our home. Dear God -- forgive the Bidenism -- this is ridiculous.
One night (May 13, 2012), I was walking through South Pasadena, CA. I was coming to the close of my walk (~5 miles) near a fire station. I decided to whip out my iPhone with the StarWalk app to look for some spring constellations that I'd never spotted before, but knew they'd be in the night sky in May.
I started with Hercules. From there, I discovered Ophiuchus, and one other. I thought to myself, "I wish I could see these stars up close". But then, the thought occurred to me that I see a star up close every day: Our sun.
I do not know why, but this started to open up the sky for me. Suddenly, the sky overhead began to seem almost 2-and-one-half dimensional. Almost three-dimensional. Hearing a star is 500ly away is one thing. Starting to get some level of comprehension of what that means is quite another. It was like looking at 35mm photos of the Grand Canyon all my life... and then seeing it with my own eyes. Yikes.
The universe's vastness became more real to me than it ever had been. This started to terrify me. The hugeness was terrifying. I had to stop, but I realized if His creation is terrifying, how much more is God?!? This is why we cannot look at him face-to-face.
Contemplating the insanity of the sizes and distances, I thought, "And Yours is the mind behind that!!" I was drawn to my knees, on the concrete, at 11pm, and worshipped tearfully for more than an hour. I could not physically prostrate myself enough. It was profoundly humbling, but not uncomfortably so. In fact, it was freaking wonderful.
Sorry, our God does not create flat earths. He's far, far, far, far more imaginative and powerful than that.
