Dearest AK-Jeff... may you have peace!
I realize your post is directed to atheists, but given what you've revealed here, may I also respond? Thank you! What am I about to share with you is not meant to sound trite, dismissive, or condescending. It is merely the truth, and I hope you can find it in yourself to listen... i.e., not just read the words, but hear what the words are trying to impart to you.
James, the brother of my Lord, may have answered your query when he wrote the following (which says pretty much the same thing regardless of the Bible version that you use):
"... if any one of you is lacking in wisdom, let him keep on asking God, for He gives generously to all and without reproaching; and it will be given him. But let him keep on asking in faith, not doubting at all, for he who doubts is like a wave of the sea driven by the wind and blown about. In fact, let not that man suppose that he will receive anything from God; he is an indecisive man, unsteady in all his ways."
Part of the problem is that many do not know what faith truly is. If you ask most people, they will say that it means believing in God. And they would be partially correct but not fully. As you may be aware, someone said that the demons believe. Faith, however, is, first, one's ASSURED EXPECTATION OF THE THING HOPED FOR.
In this case, you appear to be hoping that the Most Holy One of Israel will reveal Himself to you; yet, you also say that you KNOW He won't. Does not your "knowledge" then, negate your hope? It does. It means that what you say you hope for you do NOT assuredly expect.
Faith is also the EVIDENT DEMONSTRATION OF REALITY... though NOT beheld. What does this mean? It means that although perhaps you cannot see... hear... or feel the thing "hoped for" with your eyes, ears, or touch of flesh... that thing IS evidentially demonstrated. It is not "beheld," true... but it is EVIDENCED. How? By your SPIRIT... the man that you are... on the inside. The man on the inside of the vessel that is your body of flesh... that sees, hears, feels, etc.
You see, God is not a being of flesh... but a spirit. As are you. A spirit being, residing in an physical vessel. You are NOT your body, but the "person" INSIDE your body. And it is with THAT person that you must first "exercise" faith... so as to see, hear, feel, etc., God... by seeing, hearing, feeling, etc., CHRIST... with that person. You cannot directly see, hear or feel God... not initially... without FIRST seeing, hearing, feeling Christ. Which you must transcend your flesh to do! And once you are able to see, hear, feel Christ... THEN you can "transcend" even further, to see, hear, feel God.
The reason that you cannot do it with your flesh (physical body) first is because the PURPOSE for seeing, hearing, feeling Christ... and God... is one: for the building up of the Body of Christ, which is the noblest purpose for it (helping others is the second). Many, however, have absolutely no desire to do this "work" (i.e., serve in the "temple" of God), but rather, only want the experience. So that they can say they had it... use it to impress others... make money/fame... or for their own selfish desire ("I just want to know/see/hear/feel, so I can say it's true and He's real"). But I a must ask you... what is the BENEFIT of that? Your answer will be, of course, "So that I know."
But, dear one, your knowing is of no value to anyone but you... you who don't even believe. However, the Most Holy One of Israel is not to be trifled with in that way. If He WERE to reveal Himself to you... there would need to be some BENEFIT in His doing so, a benefit MUCH greater than you. For example, a benefit to many others, those who would listen to you when you tell them of it... and perhaps seek Him also, through Christ, as a result. The benefit? The building up of the Body of Christ! More... are "added" to that Body, which is the temple of God.
Why do you not ask for that? Because you are afraid, as most are: that the Most Holy One of Israel does in fact exist, but that knowing Him... having Him reveal Himself to you... might result in some debt to HIM, on your part. I.e., you MIGHT have to tell others, and then they'll think YOU a fool... as you thought such of others. And more than anything else in the world, you don't want to look like a fool... again, if ever.
But truly, dear one, that really is what this is all about. That is what the love of God is... and what love FOR God is: foolishness. Him for us, and we for Him, through Christ. Because that is what LOVE is all about: being willing to look foolish, indeed BE a fool... for the one you love. TRUE love has no limit on such a thing: it believes all, bears all, hopes all... and never fails. EVEN... when the one doing the loving looks like a fool. Human parents do it for their children, just as the Most Holy One of Israel does it for His. Humans do it for a spouse, just as Christ DID it for us.
So, I challenge YOU... just as you have challenged the Most Holy One of Israel, JAH of Armies: if you TRULY want Him to reveal Himself to you, put aside your pride... and your fear. Of appearing foolish... and perhaps of having to become His servant. Because those are the main things standing in your way. Thus, it is, first, your lack of faith that stands between you and the Most Holy One of Israel, JAH of Armies ("for those approaching must believe that He IS"), your approach, second (because you MUST approach, through Christ and, based on your post, you did not "enter" through that One), and perhaps, what was stated by Isaiah at Chapters 58:1-59:4.
If you are serious, then, I offer you the following:
1. First, read Isaiah 58:1-59:4
2. Then, read "John" 14:1-16:33
3. Go the One whose words were recorded in both instances, the One appointed by God as man's "mediator," Christ, and ask him to grant you entry before the Most Holy One of Israel, JAH of Armies
4. Then go to God. Let Him know that you are coming THROUGH His Son... and that you want Him to send you HIS Truth
5. And then EXERCISE FAITH in that hope... by allowing yourself to BELIEVE that such Truth WILL be sent to you
6. And when that One arrives (John 14:6)... LISTEN TO HIM (Matthew 17:5). ASK him to identify himself, to reveal to you who he is... and then DON'T dismiss his words to you. Rather, allow yourself just one moment of "foolishness" and ANSWER him when he calls and then LISTEN to what he says to you. No one will know but you and him, unless you CHOOSE to reveal it, so what have you to lose? Nothing more than a moment of your time. What, however, have you to GAIN?
7. Then DO what he directs you to do.
Because THAT... is how you EXERCISE... your faith.
May the undeserved kindness and mercy of my God and Father, the MOST Holy One of Israel, JAH of Armies, and the love and peace of His Son and Christ, my Lord, the Holy One of Israel and Holy Spirit... be upon you... if you truly wish it. If so, may YOU hear the words of that One when he and his Bride say to YOU:
"Come! Take 'life's water'... the holy spirit of God... which spirit is poured out from the innermost parts of the His Son... the Tree of Life and Rock-Mass from which all those who wish to be "cured" MUST eat and drink... free!"
