Do you not hunger and thirst after righteousness? And, I pray you, saith not He who cannot lie, that such are happy? (Matt. 5:6). How in heaven should God wipe away all tears from your eyes, if on earth you shed no tears? How could heaven be a place of rest for you, if you find rest on earth? How could you desire to be at home there, if in your journey here you find no difficulty, distress or grief?
