Such also is the natural history of calamity. The changes which break up at short intervals the prosperity of men are advertisements of a nature whose law is growth. Every soul is by this intrinsic necessity quitting its whole system of things, its friends and home and laws and faith, as the shell-fish crawls out of its beautiful but stony case, because it no longer admits of its growth, and slowly forms a new house. In proportion to the vigor of the individual these revolutions are frequent, until in some happier mind they are incessant and all worldly relations hang very loosely about him, becoming as it were a transparent fluid membrane through which the living form is seen, and not, as in most men, an indurated heterogeneous fabric of many dates and of no settled character, in which the man is imprisoned. Then there can be enlargement, and the man of to-day scarcely recognizes the man of yesterday. And such should be the outward biography of man in time, a putting off of dead circumstances day by day, as he renews his raiment day by day. But to us, in our lapsed estate, resting, not advancing, resisting, not cooperating with the divine expansion, this growth comes by shocks.
