To "Fear God" is simply fearing disappointing him as a child "use to" fear their parents...these days child do not fear their parents or have any respect and therefore continue about their lives unguided.

If you are in "Fear" of God you won't want to disappoint and will always be mindful of what pleases and displeases...in saying that we are all imperfect and he is a forgiving God.

People get so hell bent of complicating his simple instructions and trying to find cryptic/hidden messages!
