So you assume a supernatural God that communicates, and then assume natural methodology
I, for one, don't assume that. Firstly, I don't even think you have a coherent, positive definition of 'supernatural' to begin with, nor an identifiable mechanism by which the supernatural may causally integrate with nature. Secondly, when you assert the existence of the supernatural - something 'outside' the natural order, and entirely different in kind from it - you don't get to take advantage of
anything natural to explain how it works or how information about it is gleaned.
You need to establish a 'supernatural' epistemology. And it's not enough to say a god would be capable of communicating directly to you via revelation, such that your senses wouldn't be part of the process.
Even granting a positive, coherent definition of 'supernatural'
and a mechanism by which it may causally integrate with nature, you are still left with a lot of groundwork to cover. How do you discern the truth value of one revelation over another? How do you discern a revelation from something you may merely be imagining? If you are receiving testimony about
someone else's supposed revelation, how do you discern
their revelation from something they may be imagining, or lying about? How do you know there aren't other supernatural beings capable of giving revelation, and that yours isn't from one of them? Even if your god is the only one who can give revelation, how do you know he's not lying? Remember - when you provide your answers, don't invoke
anything of the natural order, lest you contradict yourself.
These are just a few of the hurdles you will have to overcome before I could even consider 'borrowing' from your worldview, as your favorite apologetic asserts.
Romans 1:18 For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, 19 because what may be known of God is manifest in them, for God has shown it to them. 20 For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead, so that they are without excuse, 21 because, although they knew God, they did not glorify Him as God, nor were thankful, but became futile in their thoughts, and their foolish hearts were darkened. 22 Professing to be wise, they became fools, 23 and changed the glory of the incorruptible God into an image made like corruptible man–and birds and four-footed animals and creeping things."
According to the Christian worldview, the evidence from creation is sufficient to leave men without excuse.
So the assertion is that people who claim to be atheists have a knowledge of this god, but willfully 'suppress' that knowledge. In other words, you've predicated an assertion on the content of my own thoughts, something you have no access to.
Bad move. To disprove this assertion, all I have to do is be aware of at least one person for whom it is not true. It so happens that I am aware of one such person - me. I have no knowledge of
any god, Yahweh or otherwise.
An equivalent scenario would be if you claimed to be able to read minds, and stated 'just now, you were thinking of picking apples in an orchard.' Since I have an immediate apprehension of my own thoughts, I am therefor in a position to know, with 100% certainty, if your claim to be able to read minds is true or false. And if I wasn't thinking of picking apples in an orchard, I know for a fact that you do not have the ability you claim to have.
So the very best scenario for you is that you've misinterpreted this passage, and your worldview is false because it depends on this interpretation. The worst scenario is that you are correct in your interpretation, and it's the Bible itself that's false, and your worldview is false because it depends on the Bible being the 'perfect word' of Yahweh.
This is rather unsophisticated question, nevertheless, which came first, the chicken or the egg?
The egg, by millions of years.
