When I contemplate the rapidity with which the great and glorious day of the coming of the Son of Man advances, when He shall come to receive His Saints unto Himself, where they shall dwell in His presence, and be crowned with glory and immortality: when I consider that soon the heavens are to be shaken, and the earth tremble and reel to and fro; and that the heavens are to be unfolded as a scroll when it is rolled up; and that every mountain and island are to flee away, I cry out in my heart, What manner of persons ought we to be in all holy conversation and godliness!
