Jeepers, dear 'pipe, you speak of God in the plural here. That is difficult for me to conceive; for I'm "all in" mind, heart, soul, and strength with the Shema: "The Lord thy God is One God" [Who expresses Himself to human comprehension as three substantively indivisible Persons].
The Oneness of God entails that any other "gods" are pretenders, false gods. [Take Allah, for instance. And IMHO, even Buddha has his limitations. But we won't even "go there" in this writing.]
I do take your point about the "atheist position": The main point of denying or "forsaking God" is to create a vacuum into which human cupidity and will to power can rush, without any possible limitation or resistance.
It's at that point that we enter into an inverted, "looking glass" world, a "second reality" that has no conceivable foundation in truth whatsoever....
Even an atheist must know that God "exists." Otherwise, why would he contend against Him so relentlessly, so mightily or from my point of view, so tiresomely and pointlessly?
Thank you for the cite to Romans 1:21. It captures the point under contention perfectly.
JMHO FWIW
Thank you so much for writing, dear brother! HUGS!!!
Romans 1:20 does indeed drive the point home beautifully! Thank you so much, dear hosepipe!
