Visionary,
If the Lord took you in vision to the courts of heaven, if you sat at the feet of Jesus while there you asked all the questions you could think of, would you be able to answer all the world's questions. Would you get them all right? Would you know all the truth? Would you only know that which the Lord has shown you?
The following is a portion of an experience I had in December 1994:
"I did emerge on a "shore" which was the shore of infinity. There I was met by Biblical Prophets, 2 of which were John the Baptist and the Apostle Paul. The latter told me that this was the place he had been on his journey, he called it the "3rd Heaven" in II Corinthians 12:1 - 4. He had entered Paradise, hearing unspeakable things it was unlawful (not permitted) to utter.
In fact, I was not allowed to speak of this to anyone for at least 10 months. Not that anything bad would happen, but thats just how it went. At one point I felt very detached and percieved Earth so far away, back through all those multi-realms. For a moment I literally felt and heard every Truth, every Lie, and every Thought ever uttered by every living being, everywhere. this lasted only one to two seconds. Then I experienced what I can only describe as a "brain circuit overload" and my consciousness snapped back into my body. The journey back didn't take long, only seconds, whereas the journey out took many minutes, perhaps an hour.
I wrote down what I had just experienced. It was a mind shaking experience - free of any drugs, and beyond anything one would experience with drugs. Indeed, only a Soul and Spirit free of intoxication could even enter such a place and percieve the forms accurately."
Bottom line is, I think we can only know what our brains are capable of. since we are not God, nor are we "gods" we can never comprehend EVERYTHING. But what we do come away with after such experiences still is awesome, though limited by our human nature and mental capacities....
