God exists. God exists before anything else. And by ‘anything else’, I mean everything that we see and observe on earth, in the skies with our telescopes, and under the seas with our cameras. This Altogether Other, the infinite-personal God of Judeo-Christianity created ‘from nothing’ everything that is ‘there’, including man in His image.
Suppose there is this Altogether Other who is omniscient in knowledge, omnipotent in power, and ultimately defined as 'LOVE", perfect in every way our minds can conceive of perfection. Eternal, from which there is no cause, always having been there. Then suppose He created ‘from nothing’ everything that now exists, including man and woman.
Now suppose, because He is infinite, everything else would be limited in contrast to His enough-ness, or infinite-ness. Man and woman are created as personal on the side of His personalness, yet finite as opposed to His infinite-ness. Would it be strange to think that this infinite, uncreated Personal Other, would not want to communicate to the created, limited personal to which He has created? To tell them of what He has done, the nature of the things around them, and something of Himself as their uncreated Creator? Of course, if this uncreated Personal Other were to communicate to this created personal, He would not exhaust Himself in His communication, but would tell her things that are true. He would not lie, for what would be the purpose?
It would also not be unexpected, if the uncreated Personal really cared for the created personal, to speak of things in a propositional nature; to communicate in the same way that the created personal communicates to other created personals. As a limited, finite reference point, the created personal if she began with herself, would not be able to know everything there is to know about everything if this uncreated Personal didn’t tell her those things. Of course, she wouldn’t know everything because that would make her God, wouldn’t it, but at minimum she would know those things that the uncreated Personal wanted her to know, and those things He wanted her to know would be true. Because He created the world she lives on, and the universe she lives in, He would also create in her a spirit of discovery; a rational mind to uncover other things about herself and the world around her. Her knowledge of those things would need to be in relation to Him; analogical to His knowledge though for them to be true to what is, and true to His creation of those things in the first place.
What we have in the above then, is exactly what the Judeo-Christian Scriptures, the Bible, claims for itself. It claims to be propositional revelation from the uncreated Personal Other to the created personal in verbalized form. God speaks, and we have His knowledge as non-created Personal, perfect and infinite, to tell us what He wants us to know as the created, finite personal.
