And recall when you told Moses, " We won't believe in you until we see Allah face to face." (This happened because you had programmed your minds into the primitive ways of the "age of worship" when humans could only appreciate the tangible. At that level of intellect, humans come to fear natural phenomena). Thus, when you saw the lightening thunder (and the challenges of life) you almost fell dead in fright. (Losing your reason (7:155)).
