Divine Hiddeness

Here's the problem, as an orthodox Christian I believe God to be the greatest possible being. This includes God as omnipotent, omniscient, and omnibenevolent (or all-loving). I believe God to be a spiritual being, who is incorporeal, and is certainly not less than a person, if He isn't a person. So why is it so difficult to prove that God exists? Why does evil exist? Why doesn't God answer all our prayers? Why doesn't God just come to us and say, "I exist?" This is the problem of divine hiddeness.

Yesterday I claimed that the default position for theistic belief is agnostic, which would be religious skepticism, not knowing whether a deity exists. Agnostics don't need arguments for their beliefs; atheists do need arguments for their beliefs. Just want to classify the distinction between the two. I think that Romans 1 would present a case for theism being a default position, but I will concede ground and claim that for sake of argument agnosticism is a default position. So here is the case of a garden as told by Anthony Flew which illustrates the problem of divine hiddeness:

Two mountain hikers were hiking through the wilderness and came to a garden. There were plants organized neatly and orderly and looked like they were well maintained, but along with the plants some weeds were also mixed in. One of the hikers said to the other that there was a gardener who took care of this garden and that it was obvious because of the design in the garden. The other hiker claimed that it was chance that had brought this garden about and that there was not a gardener because the weeds were too numerous. So they both sat and waited for weeks waiting to see if the gardener came. The one who believed that there was a gardener claimed that the gardener must be invisible and that's why we never see him....

Well this illustration continues on, but you get my point. It is difficult for us to know what God is doing. I suppose this allows us to trust in God more fully, but maybe not. If more people would believe in God if He revealed Himself to every generation would that change things. Obviously Jesus Christ, God Incarnate, the Word became Flesh, is God on earth and people even then refused to believe in Him. As God tells the rich man who is in hell and thristy (in the parable about Lazarus) if they didn't listen to Moses or the prophets, why will they believe you?

Maybe that's the problem, God has given us signs but we just don't read or believe them correctly.
