We have now reached the close of the longest and most important section of the Apocalypse, beginning, as has been already pointed out, with chap. vi. It is the fourth in that series of seven of which the book is composed; and the main purpose of St. John in writing finds expression in it. As the writer of the fourth Gospel describes in the fourth section of that book, extending from chap. v. to chap. xii., the conflict between the Son of God and "the Jews," so he describes in the corresponding section of the Apocalypse the conflict between the glorified Son of man as He lives and reigns in His Church and the evil of the world. Throughout the conflict we are not once permitted to forget that, although Christ and the true members of His Body may be the objects of attack, and may even have to retire for security from the field, God is on their side, and will never suffer His faithfulness to fail or forget His promises. In a threefold series of judgments the guilty world and the guilty Church are visited with the terrors of His wrath. These three series of judgments, too, go on in an ascending line. The climactic character of their contents has already been pointed out, and nothing more need be said of it. But it may be worth while to notice that the element of climax appears not less in the nature of the instruments employed. Comparing the Trumpets with the Seals, the simple fact that they are Trumpets indicates a higher, more exciting, more terrible unfolding of wrath. The Trumpet is peculiarly the warlike instrument, summoning the hosts to battle: "Thou hast heard, O my soul, the sound of the trumpet, the alarm of war;" "That day is a day of wrath, a day of trouble and distress, a day of wasteness and desolation, a day of darkness and gloominess, a day of clouds and thick darkness, a day of the trumpet and alarm against the fenced cities."[494] That the Bowls, again, are still more potent than the Trumpets, appears from the language in which they are described, from their mode of introduction, and from the vessels made use of for the plagues. They are "the last" plagues; in them is "finished" the wrath of God; they are called for by a "great voice out of the sanctuary;" and they proceed, not from a secular instrument, however warlike, but from a sacred vessel, not from one which must be sounded for a length of time before it produces its effect, but from one which, inverted in a moment, pours out with a sudden gush its terrors upon men. Similar though they thus are, the three series of judgments lose what might otherwise be their sameness; and the mind is invited to rest upon that most instructive lesson of the providence of God, that in proportion to privilege misused is the severity with which sin is punished. Throughout all these judgments the righteous are kept safe.
