God can be known to us in the same way as a man can see an endless ocean by standing at the shore at night with a dimly lit candle. Do you think he can see much? Not much, almost nothing. And nevertheless, he sees the water well. He knows that there is an ocean in front of him, that this ocean is huge and that he cannot see it all at once. The same is true of our knowledge of God.
