It is also impossible to substantiate God in the mental or psychological realm. His wisdom is too great for the limited mind of man to comprehend. We have not yet explored all the different forms of life on this planet, including micro-organisms and mammoth creatures of past and present. We have not yet fully explored the microcosm and macrocosm of this universe. We have not yet fully unearthed our own past history, nor can we be certain of what will happen in our future, even in such simple matters as the weather or the timing of the next earthquake.
Finite beings have a natural limitation comprehending the infinite One.
It is harder for a man to understand God than it is for a worm to understand man. Contacting God with the Human Spirit Man lives in the physical and psychological realms, but God is in the spiritual realm. Therefore, man cannot physically sense or logically prove God, but we are not saying that it is impossible to contact God or to verify His existence. It is possible when we use the right organ. Whoever seeks Him will find Him.
