Would evidence of God make a person turn away from their sins? Some may out of fear for their lives. They might be inclined to follow the letter of the law to avoid punishment. What does that gain God? Slaves? If the slaves were left alone and the threat of punishment were removed would they not return to their old ways?
God can provide evidence but he does not. Does not this mean that God gains some advantage by not providing it? What advantage does God gain by remaining hidden? What negative consequences would there be if God was no longer hidden?
I may be mistaken, but what occurred to me a few weeks ago is that, God cannot, by evidence, prove that He actually is God to an atheist or skeptic.
If God shows shows he can rearrange universes, maybe he’s just a very powerful being (like Q from Star Trek) masquerading as God.
If God shows He can read your mind, that might just mean the being you’re talking to is psychic.
If God predicts the future correctly, perhaps He’s just a time traveler or experiences reality in another way.
I can keep going all day, but the point is, it doesn’t matter how much power a being shows, the being cannot prove the being is God by observable evidence. God can’t prove Himself to an atheist.
I have a theory, and I don’t know if it’s theologically sound or anything, but I think part of why God “hides” Himself, is that, by “hiding” himself, God allows free will able to exist. Because, by revealing Himself, goodness is revealed to an individual, and when confronted with absolute truth, the person is forced to make a decision that will forever change the course of their life, and narrow the path - and their amount of freedom.
Perhaps by “hiding” Himself, God lets man able to freely seek Him if they really desire to find God and goodness. Perhaps if God keeps talking to fallen mankind over their shoulder admonishing them 24/7, it would only make mankind more rebellious to authority than they already are, feeling they have no freedom.
Satan rebelled, along with I think a third of the angels? God was not hidden from them, yet they stilled rebelled.
In the end, I feel the only thing that can convince a sincere doubter is an infusion of grace, backed by a honest pursuit of truth, faith and reason. It’s all in God’s hands.
