According to C.S. Lewis, "we are not necessarily doubting that God will do the best for us; we are wondering how painful the best will turn out to be."

I think sometimes we think the best must equal a state of being pain free, and/or happiness (in the worldly/circumstances sense) etc. And when life doesn't look or feel like that we naturally think God must be holding out on us. Obviously this can not be his best.

But sometimes the best is painful. Sometimes the best is a process. Sometimes the process is painful. But it's still the best.

Boy is that hard to believe/remember on a daily 'in the midst of' basis.
