Are you saying, for example, that we can observe the stars and galaxies, and how the planets are spinning globes with orbiting moons, and be wrong to assume that the earth shares such similar properties?
God specifically ordained that they have a function and a purpose, which is not necessarily shared with the earth itself. It's like I mentioned earlier about the lightbulb and the floor. Just because some stellar object in God's creation possesses certain properties, does not mean the earth possesses the same.
Who established the earth above the waters: for his mercy endureth for ever. Who made the great lights: for his mercy endureth for ever. The sun to rule over the day: for his mercy endureth for ever. The moon and the stars to rule the night: for his mercy endureth for ever. [Ps. 135:6-9]
And God said: Let there be lights made in the firmament of heaven, to divide the day and the night, and let them be for signs, and for seasons, and for days and years: [15] To shine in the firmament of heaven, and to give light upon the earth. And it was so done.
And God made two great lights: a greater light to rule the day; and a lesser light to rule the night: and the stars. [17] And he set them in the firmament of heaven to shine upon the earth. [18] And to rule the day and the night, and to divide the light and the darkness. And God saw that it was good. [Gen. 1:13-18]
Note how he doesn't say worlds, or planets, but lights for the purpose of time-keeping, the seasons, etc.
I don't think the flat earth model does God's infiniteness any justice compared to the globe earth model, but I could see it doing justice to His almighty power to order things in a way that seems to defy the logic, math, and observable universe that we know.
I would argue it does a tremendous justice to God's infinitude because it shows that the creature is finite in light of the Creator.
The funny thing about defying logic is that it actually
affirms logic in God's creation to have a flat plane. The world we stand upon appears flat, because it most likely is flat. It's a simpler explanation, and therefore, more logical, than to say that we are on a spinning globe hurdling through space (as moderns claim).
In a FE we have a definitive direction for up, and down; rather than the illogical assertion that there is no true up or true down; or that water can curve around a spherical object; or that there's some mysterious "force" or "curving of space-time" that strongly affixes some objects to a surface, but fails to affix some weaker objects, etc.
I would consider it a miracle for the sun to hover in a circular path over the flat earth with the moon, changing its position with the seasons.
And not to deflect from the topic here, but since you mention miracles, I've pointed out that previously that, in a way, the miracle of the Sun in Fatima implicitly affirms the notion that the Sun is a local body that moves through the sky; rather than a massive object millions of times the size of our world, millions of miles away. It's an interesting thought, especially since it precedes the deception of NASA to follow only a few decades after the fact.
And the same can be said about the miracle of Josue where he prayed to stop the Sun. (Josue 10)
