Don’t think such heavenly mindedness makes us pilgrims no earthly good. Don’t pooh-pooh it as looking at the world through pie-in-the-sky, rose-colored glasses. Sojourners who think the most of the next world are usually those who are doing the highest good in this one. It is the person whose mind is only on earthly things who, when it comes to earth, does little good.
