How to know?

"CRITIAS: 'Here then, Socrates, is the plan we have made to entertain you. We thought that Timaeus, who knows more about astronomy than the rest of us and who has devoted himself particularly to studying the nature of the universe, should speak first, and starting with the origin of the cosmic system bring the story down to man.'" - Plato, Timaeus, pg. 40

Of course apart from Revealed truth no one knows God. Who can pry into the mind of God? No one. God alone reveals secrets. The history of worldly education is that it is done apart from God and His word. Instead man has endeavored to know the hidden things by what he sees on earth. The grave question to ask is how do you know? The epistemic question is important in knowing anything at all. How does one derive his or her knowledge of the universe, what Method is used to gain knowledge? The Christian knows truth by the word of God and by faith we know that God created the universe.
