Purpose of Difficulty
Sorrow and difficulty are going to be parts of our lives. We waste our mind's thoughts when we think that these things ought not to be. That is a waste because they simply are parts of life. The real question we want to pose to ourselves is, "How will I be after this and through this? What is God forming in me that will change me into a new creation?" I am being made new, and my sorrow and difficulty are the pressing things, which God uses to make me who I am becoming from His design.
