   God will in some way or other direct the steps of those who
   acknowledge him in all their ways, and seek unto him for
   direction with full purpose of heart.  Sometimes we find most
   comfort in that which is least our own doing, and into which
   we have been led by the unexpected, but well observed, turns
   of Providence.
