Why assume that “everyone” wants to hear from God? There have to be some people who would not want to hear from God. God is All-Knowing so God knows that. God wants belief to be a choice and that might be one reason God does not speak directly to everyone.
However, that is not the main reason why God does not speak directly to everyone, because hypothetically speaking, even if God spoke directly to everyone, people could still choose not to listen or hear.
Imo, the main reasons why God does not speak directly to everyone are as follows:
- God wants us to seek Him out and use our innate intelligence to decide if we have found Him. God rewards true seekers.
- God does not want to make belief easy to acquire. God wants us to exert an earnest effort in order to believe.
- God wants us to have faith that He exists without absolute proof. Those who have faith will get the proof they need.
- Last but not least, nobody except God’s Messengers can comprehend God. Messengers act as mediators between God and humans, communicating what we would otherwise be unable to understand.
I can find no reason at all to suppose any of your "reasons" have any basis in reality. God has the ultimate "bully pulpit," if he chooses to use it. Presidents, prime ministers, despots and tyrants all have their own bully pulpits -- they can take over the television and radio channels and deliver their message to everybody. And they do it, sometimes. Sure, some people don't listen, and some don't agree, but what does that have to do with the fact that the message can be delivered to, for all practical purposes, everybody?
Why would you imagine "God wants us to seek him out?" For goodness sake, why would you even suspect that some early human, eating a few locusts and roots on the plains of Africa, would even suppose that there's "somebody to look for?" What hints does he have, as his first 2 children die before they reach the age of 2 days, that such a being exists? What would make them even suspect it?
Whatever God wants about the making "belief easy to acquire" is moot, because we humans are capable of believing the most absurd crud possible -- and we do it all the time.
What is the benefit of "faith without proof?" What do you get from that? What comes of the "faith that the rains will come" if the rains don't, and you don't have anything stockpiled to feed you for the year? That -- any cretin could see -- is a total failure founded in faith. And humans, to their credit, figured that out long ago, and learned how to prepare for the times when things don't happen as they usually do.
And I think it is axiomatically idiotic to suppose that there are some humans -- humans like you, and like me, who live, eat, **** and die -- who have some special understanding of "God" that is not available to the rest of us. You have quantitatively zero evidence for any such thing, except for the claims of those who -- ironically -- did live, eat, **** and die, often unpleasantly. And who all disagreed with one another on their "understanding of God," which is proof positive to any thinking person that, tragically, they lacked any such understanding at all.
