Personally, I think, if I found out that somebody didn't believe in me, that wouldn't make it difficult for me to believe in them. I could still, say, speak to them. I could still walk up to them and see them and talk to them.
Why would a human have so much power over a god, that the human's disbelief would render the god impotent and mute?
I think this is a question that deserves much more attention than it receives! I can't be sure that you personally are asking it in rhetorical fashion, but usually when I see this type of thinking, it is expressed that way.
There are of course drastically different ways of approaching your question, which is what makes a forum like this so interesting. Unfortunately, in this sub-forum we normally see 1 Christian POV per about 4 atheists, and in the C only sections we get no atheist POV to balance things out. So I reserve the right to present at least a couple different mindsets
1) God GAVE mankind dominion. I'm not sure how to place enough weight on this one point, or if you (or any other poster) really understands the significance of this, but there ya go. With dominion, an atheist declares God does not exist, and He respects that choice; the Holy Ghost is a gentleman.
2) God doesn't believe in atheists. I'm pretty sure this phrase was coined as comic relief for a tense subject, but there is a lot of revelation to develop this angle.
3) Knowledge = power. Power must be kept from the hands of those that would misuse it. This isn't E & M, but this angle quickly gets touchy.
4) God works by Faith. There were region Jesus on earth "could not" ... perform many miracles.
5) Who is to say God does not speak to atheists sufficiently?
" The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. [There is] no speech nor language, [where] their voice is not heard. Their line is gone out through all the earth, and their words to the end of the world." (Psalm 19)
"Lady Wisdom goes out in the street and shouts.
At the town center she makes her speech.
In the middle of the traffic she takes her stand.
At the busiest corner she calls out:
Simpletons! How long will you wallow in ignorance?
Cynics! How long will you feed your cynicism?
Idiots! How long will you refuse to learn?
About face! I can revise your life.
Look, I'm ready to pour out my spirit on you;
I'm ready to tell you all I know.
As it is, I've called, but you've turned a deaf ear;
I've reached out to you, but you've ignored me.
25-28 "Since you laugh at my counsel
and make a joke of my advice,
How can I take you seriously?
I'll turn the tables and joke about your troubles!
What if the roof falls in,
and your whole life goes to pieces?
What if catastrophe strikes and there's nothing
to show for your life but rubble and ashes?
You'll need me then. You'll call for me, but don't expect
an answer.
No matter how hard you look, you won't find me.
29-33 "Because you hated Knowledge
and had nothing to do with the Fear-of-God,
Because you wouldn't take my advice
and brushed aside all my offers to train you,
Well, you've made your bednow lie in it;
you wanted your own waynow, how do you like it?
Don't you see what happens, you simpletons, you idiots?
Carelessness kills; complacency is murder." (Proverbs 1, from The Message)
