Why ask Why

Why is it that when things don't go our way we question God? Why do we think that He has to protect us from all the evil in the world, when we are the evil of the world. Why do we question God's intentions when we can't grasp how infinite He is and how this whole world does not revolve around us? Why do we say.... If this happens, I will be happy.... when we should be happy with all that the Lord provides? WHY WHY WHY? Why do I EXPECT Him to pour blessings on to me when so many times a day, I fall short.
