Most of the Epistles were written in a prison. The greatest thoughts of the greatest thinkers have all passed through fire. When God is about to make pre-eminent use of a person, He puts them in the fire. Great minds have purposes, others have wishes. We have all of us sufficient fortitude to bear the misfortunes of others.
Life is a long lesson in humility.
The tests of life are to make, not break us. Trouble may demolish a person's business but build up their character. The blow at the outward person may be the greatest blessing to the inner person. If God, then, puts or permits anything hard in our lives, be sure that the real peril, the real trouble, is that we shall lose if we flinch or rebel. The only good luck many successful people have is the ability and determination to overcome bad luck.
