Who understands?

A couple years ago I was reading through Proverbs and came across Proverbs 14:10 which says:

"Each heart knows its own bitterness, and no one else can share its joy."

Up to that point in my life I had not experienced the trials which cause true anguish to one's soul. The older I grow, the more I experience life's difficult and painful times. I have seen painful and seemingly unfair sorrows burden my friends. I myself have been pained. As I try to comfort those around me and others try to comfort me I am struck with the reality of this verse. No matter how much effort a person extends one can never truly understand the pain of another heart. I have tried. I can imagine, I can place myself in the other person's shoes, I can hurt for them, but I can never know their sorrow and bitterness. There is no one who understands. No one except our Heavenly Father.

"O Lord, you have searched me and you know me. You know when I sit and when I rise; you perceive my thoughts from afar. You discern my going out and my lying down; you are familiar with all my ways. Before a word is on my tongue you know it completely, O Lord." Psalm 139: 1-4

God knows man better than he knows himself because God created man. God knows my thoughts and before I even speak He knows what I am going to say. He truly knows me, which means he fully understands my pain. He doesn't have to imagine or try to put Himself in my shoes. Who understands? God understands.

 "Search me, O God, and know my heart; test me and know my anxious thoughts." Ps.139:23
