during days of robust health.  And what does all this prove but the momentous truth, that anything which once was done,—­anything which we have ever thought, uttered, or known, or was ever inscribed in the book of memory,—­remains there engraven in characters more permanent than those which, cut deep in the hoary monuments of Egypt, have outlived teeming centuries of human history?  Darkness may cover the page, but by a vivid and mysterious flash every letter is illuminated.  That flash may be only some trifle, such as a note of music—­the tone of some voice—­

  “The subtle smell which spring unbends,
  Dread pause abrupt of midnight winds,—­
  An echo or a dream!”

And thus may it be at judgment; by the extension of the same kind of power, may our whole life, in its minutest details, pass before our eyes,—­each minute of it delivering its own history of word or deed, of things done or things received,—­and each recognised as true by the possessor of them all.  Accordingly, every man is now, whether he wills it or not, unconsciously writing or daguerreotyping his own biography;—­his whole life forming a work of more importance, to himself at least, than any other in the universe,—­each volume a year, each chapter a month, each day or hour a page.  At judgment memory will read the whole, and be compelled to feel that every word is true.  It is strange, too, how rapid—­reasoning from analogy—­such a review may be, without diminishing from its distinctness.  States of being, or successive acts, which occupied long periods of time, may very rapidly be recalled in all their minute features.  In moments of sudden peril, when death seemed approaching, how frequently have men told us that they beheld, in a twinkling of an eye, the great features of their whole life like a panorama passing before their mind’s eye!  And thus at judgment, clear, yet rapid—­intensely real and vivid, yet sudden as light—­may the life of the boy, and the man, and the patriarch, from, the first till the last moment of conscious and responsible existence upon earth, be presented to the mind with a self-evidencing power of truth, which cannot, which dare not, be denied or resisted!  Jesus Christ will speak to the man from within the man, and, with irresistible power, say to him, “Son, remember!”

3. The Book of Conscience shall be opened.—­This will afford abundant evidence, when read along with the books of memory and providence, of the witness in every man’s soul for the moral government of God, and that ever accused or excused his life.  That tremendous power which has dogged the murderer in his flight, following him across the seas, tracking him to his refuge in some solitary island or savage wilderness,—­that presence which, like an evil spirit from another world, has disturbed the guilty in the midst of his festivities, or sat heavily on his soul, brooding over him in his slumbers as a horrible
