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 shellfish 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 coöperating with the divine expansion, this growth comes by shocks. We cannot part with our friend. We cannot let our angels go. We do not see that they only go out, that archangels may come in. We are idolaters of the old. We do not believe in the riches of the soul, in its proper eternity and omnipresence. We do not believe there is any force in to-day to rival or recreate that beautiful yesterday. We linger in the ruins of the old tent, where once we had bread and shelter and organs, nor believe that the spirit can feed, cover, and nerve us again. We cannot again find aught so dear, so sweet, so graceful. But we sit and weep in vain. The voice of the Almighty saith, "Up and onward forevermore!" We cannot stay amid the ruins. Neither will we rely on the new; and so we walk ever with reverted eyes, like those monsters who look backwards.
