I wonder what we would view David;s coping skills.

Reading Psalms, he was very vocal about his emotions and quite comfortable with saying to God "I'm lonely" or "THis stinks that the bad guys aren't getting what's due them". He was VERY clear with proclaiming God's mighty hand in all things at the end of his psalms. Paul was honest about the pain and frustration his thorn caused him.
We need to get rid of the notion that we are going to be free of struggle in this life.
But I also think it is clear from scripture that we need not project a forced "Stepford wives-I'm always happy and in control". God wants to hear our sorrows and frustrations and pain....but David's example shows that even this vocalization is directed toward GOd and understanding His plan and purpose.
