Not being able to fully understand God is frustrating but it is ridiculous for us to think we have the right to limit God to something we are capable of comprehending. What a stunted, insignificant god that would be! If my mind is the size of a soda can and God is the size of all the oceans, it would be stupid for me to say He is only the small amount of water I can scoop into my little can. God is so much bigger, so far beyond our time-encased, air/food/sleep-dependent lives.
