Our tendency in the midst of suffering is to turn on God. To get angry and bitter and shake our fist at the sky and say, "God, you don't know what it's like! You don't understand! You have no idea what I'm going through. You don't have a clue how much this hurts."
The cross is God's way of taking away all of our accusations, excuses, and arguments.
The cross is God taking on flesh and blood and saying, "Me too.” ~Rob Bell
