Growth comes through opposition

Therefore, how can you and I really expect to glide naively through life as if to say, 'Lord, give me experience but not grief, not sorrow, not pain, not opposition, not betrayal and certainly not to be forsaken. Keep from me Lord, all those experiences which made thee what thou art. Then let me come and dwell with thee and fully share thy joy.'
- Elder Neal A. Maxwell

A God who is asking nothing of us is making nothing of us.
