18 For the day cometh that the Lord shall utter his voice out of heaven; the heavens shall shake and the earth shall tremble, and the trump of God shall sound both long and loud, and shall say to the sleeping nations: Ye saints arise and live; ye sinners stay and sleep until I shall call again.
19 Wherefore gird up your loins lest ye be found among the wicked.
20 Lift up your voices and spare not. Call upon the nations to repent, both old and young, both bond and free, saying: Prepare yourselves for the great day of the Lord;
21 For if I, who am a man, do lift up my voice and call upon you to repent, and ye hate me, what will ye say when the day cometh when the thunders shall utter their voices from the ends of the earth, speaking to the ears of all that live, saying—Repent, and prepare for the great day of the Lord?
22 Yea, and again, when the lightnings shall streak forth from the east unto the west, and shall utter forth their voices unto all that live, and make the ears of all tingle that hear, saying these words—Repent ye, for the great day of the Lord is come?
23 And again, the Lord shall utter his voice out of heaven, saying: Hearken, O ye nations of the earth, and hear the words of that God who made you.
24 O, ye nations of the earth, how often would I have gathered you together as a hen gathereth her chickens under her wings, but ye would not!
25 How oft have I called upon you by the mouth of my servants, and by the ministering of angels, and by mine own voice, and by the voice of thunderings, and by the voice of lightnings, and by the voice of tempests, and by the voice of earthquakes, and great hailstorms, and by the voice of famines and pestilences of every kind, and by the great sound of a trump, and by the voice of judgment, and by the voice of mercy all the day long, and by the voice of glory and honor and the riches of eternal life, and would have saved you with an everlasting salvation, but ye would not!
26 Behold, the day has come, when the cup of the wrath of mine indignation is full.
