Quote: 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. — John Charles Ryle (1816–1900) English Anglican bishop
Note: Heaven will be a strange place for all of us, saint and sinner alike. The angels will help us to move from good to better to best.
