For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.
If you try to rationalize God exhaustively, you will fail. There are mysteries about God that we will never understand in this life. How can the small and finite, limited to time and space, understand an infinite God! We should not think it strange that it is impossible to explain many mysteries in the realm of matter.
Who can explain why objects are always attracted to the center of the earth? Who can fathom the law of gravity? Newton discovered it, but he could not explain it. Who can explain the miracle of reproduction? . . . Thus many evidences and many arguments could be advanced to indicate there is a God.
Yet the plain truth is this: God cannot be proved by mere rationalization. He cannot be contained in a tiny man-made test tube or confined to an algebraic formula. If God can be fully proved by the human mind, then He is no greater than the mind that proves Him.
