It is prophesied that In the end-time there is a period of Great Tribulation. At the end of this period, when an angel sounds the first of seven trumpet blasts it will usher in the Day of the Lord which lasts one year. During this period of time, as each trumpet is blown, a different earth shattering cataclysmic event will occur, whether planetary destruction, the heavens being darkened or successive world war. The seventh trumpet announces the return of Jesus Christ, the resurrection of the saints, the final wrath and punishment of God on a sinful rebellious world and the decisive victory of Christ in this last world war before a time of millennial peace and joy.
