The reason responsible as to why, despite having so very many different religions around the globe today, there’s actually only but a single God who’s directly responsible for giving us those numerous systems of belief? In only but two words: Sparking differentiation.
God provided us with so many faiths, only in order to produce stark differences across our Earthly cultures and societies -throughout every corner of the world- over several centuries & millennia. He did so such that we might become ever more distinct and unique from one another on an individual level, therefore satisfying His desire to Create and cultivate new sentient consciousness (ones ultimately joining with His plane of existence upon our mortal death in this plane).
Yet, while certainly accomplishing those ends, there was also a second reason here for giving us as many faiths as we ultimately received from God: The dynamics between different cultural and ethnic groups of human beings; those outcomes produced by way of their interactions with each other, and the near infinite societal/scientific/technological contributions derived from such interplay (which is also the bulk of what this particular piece will be dealing with, given that the former aspect hardly requires any greater elaboration than the preceding provided).
Now although there have indeed already been “unifying” sects, churches… even whole religions? If only by and large, none of those have existed in such a way as to give truly equal validity to all the major established worldwide systems of belief; never before having been anything presenting the notion that all such faiths are equally correct and valid, let alone any genuine supposition holding that all of them came to exist in our world from the very same higher power. There’s seems a very good reason for that absence: At least in theory, this might seem to be something of an outright impossibility!
It should surely appear the height of absurdity to say that the divinity of Buddhism, Sikhism, Christianity, Islam, Shintoism, Judaism, and countless more are all quite literal as a deity; with each and every last one of them having come from the same God/divine entity/higher power/what have you. To support such a supposition under the backdrop of existing theologies? One would simply have to be either delusional or something of an unrepentant polytheist – and should the latter be the case, well… have we not just annihilated all the monotheistic religions from the mix, right off the bat?
So this is where I attempt to bring this entire portion the rest of the way “home“, as it were – finally drawing everything in this section together. A critical understanding to keep in mind hereabouts should be the fact that ours is a diverse world filled with many wildly divergent cultures (never mind, on purely an individual level, how vastly differing we each are!) What’s more, the relationship those same cultures play with one another, and the countless contributions they each bring to the table that is the all of human civilization, itself…? Remove only but a single one of those from the equation, and we’d be left with a world that most certainly wouldn’t so much as merely resemble what it actually is here today!
So of course we might wonder why, given an omnipotent divinity capable of all things under the Sun, there’s no singularly dominant faith on this Earth… nor has there ever been such a thing; something that’s been enjoyed by all peoples the whole world over, at any one particular moment in time. The explanation behind such a void is actually rather deceptively simple, in point of fact, and something that was wholly intentional on God’s own part thereabouts.
Now, just try and envision that hypothetical world… one in possession of only but a singly dominant religion. Would it not be the most blandly homogeneous of places, with universal sameness abounding and individuals nary anything besides fundamental clones of one another? Had we therefore been given but a lone single such faith by God, our cultures and societies would be all but identical to each other just now; the all of human civilization nothing save for varying shades of greys (compared to the fantastically diversified rainbow it presently consists of).
