The timing of the event described in I Thessalonians 4:16-17 is crucial, and it is explicitly linked to the last trumpet. Paul states in verse 15 that this occurs at the coming of the Lord, and in verse 16, Christ descends from heaven with a shout, with the voice of an archangel, and with the trumpet of God. This last seventh trumpet, as further detailed in I Corinthians 15:50-52, announces the coming of Christ, the establishment of God's Kingdom, the judgment upon the nations, and the rewarding of the saints, all happening simultaneously. The last trumpet sounds when Christ returns, not at any prior interval. Additionally, Revelation 10:7 indicates that when the seventh angel is about to sound, the mystery of God will be finished, signifying the transformation of the saints into eternal spirit beings. Matthew 24:30-31 also confirms this timing, showing that the trumpet sounds to gather the elect from all over the earth to meet Him upon His return. Other scriptures, such as Isaiah 27:12-13, Joel 2:1-11, and Zechariah 14:3-5, 9, further support this sequence of events tied to the seventh trumpet.

The sounding of the seventh trumpet marks a pivotal moment in God's judgment. At this time, the active reign of the Son of God begins, heralding significant events. The seventh trumpet announces the return of the children of Israel to their land, a judgment by God that involves both the people and the land of Israel. This gathering is done with gentle care, as the term used for threshing indicates a delicate process, not a harsh beating, but a careful separation and purification. The children of Israel, broken in spirit through the Tribulation and the Day of the Lord, are led back one by one, as if by the hand, showing God's concern for their condition. At the sounding of the seventh trumpet, as described in Revelation 11:15-18, a distinct judgment unfolds. The nations are judged, rewards are given to the servants, prophets, and saints, implying an evaluation by God, and a further judgment is pronounced with the destruction of those who destroy the earth. Thus, the Feast of Trumpets embodies a time of judgment, culminating at the seventh trumpet with decisions reached for each person under scrutiny. Those fitting the parameters of reward will enter the Kingdom of God, while another judgment begins with the reign of the King and the destruction of the destroyers. Judgment permeates these holy days, each event building toward the ultimate reconciliation and purpose of God.

The Seventh Trumpet, as highlighted in Revelation 11:15, heralds a profound moment in God's plan, announcing the return of Jesus Christ and His assumption of rulership over the earth. This trumpet signals the onset of the seven last plagues, also known as the seven bowls or vials of God's wrath, marking a period of intense judgment upon the nations. It proclaims not only His coming but also the avenging and rewarding of His faithful servants for their patience and loyalty to God. This event ties directly to the overarching themes of the Day of Trumpets, reflecting the anticipation of Christ's return as a central focus. The Seventh Trumpet expands the understanding of the Day of the Lord, which encompasses a broader span than a single day, potentially lasting a full year under the biblical principle of a day for a year. This period, initiated by the series of trumpets and culminating with the Seventh, involves severe trials and destruction before Christ's return, affecting both God's people and the world. It underscores His actions to subdue the nations and ultimately establish His reign. Further insight into the Seventh Trumpet is seen in Revelation 16:17, where the seventh bowl is poured out, signifying an unprecedented level of destruction as God's wrath is unleashed. The imagery of mountains and islands fleeing away illustrates the immense power and terror of this time, emphasizing the total collapse of human constructs and the fall of Babylon under His fierce anger. In I Thessalonians 4, the trumpet blast associated with Christ's return is described as accompanied by the voice of the archangel, marking the resurrection of the dead saints and the transformation of the living in an instant. From that moment, they will forever be with the Lord, highlighting the ultimate hope and reward tied to the Seventh Trumpet. Revelation 19 further elaborates on the announcements made by this trumpet, portraying Christ as the righteous judge, avenger of His people, God, King, husband of the church, warrior King striking the nations, and Judge of the beast and false prophet. These roles encapsulate the multifaceted significance of His return, echoing the themes of judgment, rulership, and deliverance inherent in the Day of Trumpets.
