Approaching the King (Ecclesiastes 8:1-9)

Rulers and superiors are people who have authority.  This is an authority that can make things rather stressful for us if we try to enter into their presence because they have power to hire, fire, and even sentence.  How will they receive us?  How will they receive criticism if we have to give some? What will be the potential consequence for appearing to challenge their authority?  These are the sorts of things that the preacher in Ecclesiastes teaches us about in his sermon.  So, how do we approach the leaders of our day?
