“Most men hope to go to heaven when they die; but few, it may be feared, take the trouble to consider whether they would enjoy heaven if they got there.  Heaven is essentially a holy place; its occupations are all holy….What could an unsanctified man do in heaven, if by any chance he got there?  Let that question be fairly looked in the face, and fairly answered.  No man can possibly be happy in a place where he is not in his element, and where all around him is not congenial to his tastes, habits, and character.”
