Sorry for taking long to reply. I didn't see your reply early. Ephesians & Isaiah (Books of the bible) are talking about God (The Great "I am") & The mysteries revealed through his son "Jesus Christ". Man in his fallen state (sinful nature) cannot comprehend the value placed on him by God and the great mental, spiritual & physical abilities within his grasp as long as he does not submit to his maker. He is blind to the true nature of his environment and elements influencing his being.
