Please bear in mind that scriptures about the “trumpet of God,” “the last trump,” and “the seventh trump,” are all referencing the same trump of God, and pertain to the same time period with messages from God. None of the trumps ever issue a literal sound. (Matthew 24:31; 1 Corinthians 15:51; 1 Thessalonians 4 1:16; Revelation 8:7-13; 9:1-21; 11:15-18 ).
The seventh trumpet refers specifically to Jesus’ second advent and the Day of Jehovah. All seven trumpets of Revelation have a symbolic character and mark one of seven Great Time periods with their corresponding events. Currently, the seventh trumpet is sounding. Our Lord Jesus has brought mankind a great increase of knowledge and of travel (Daniel 12:4). This combination is resulting in the great time of trouble (Daniel 12:1, Matthew 24:30,31, Revelation 11:15,18).
More specifically, the “Trumpet of God” (1 Thessalonians 4:16) is the same “final trumpet” of 1 Corinthians 15:51, and is describing the same events: the resurrection and reward of the saints. Similarly, we believe that “God’s Trumpet” and “the last trumpet” is also the “Seventh Trumpet” of Revelation 11:15,18. During the blowing of this last trumpet, the end of the present world systems occurs with Armageddon. Subsequently, Jesus and His Church will resurrect and restore all mankind back to the perfection lost when Adam sinned. (Acts 3:19-21)
So “God’s Trumpet” introduces Christ’s judgments associated with the establishment of the Kingdom of God. (Isaiah 26:9)
Each of the seven church periods has its own seal and trumpet. The history of the church, the apostate church, and mankind are traced in the book of Revelation. Notably, the development of the “mystery” of God’s plan is hidden in figures and symbols. Revelation 5 is a symbolic description of the panorama illustrating this subject. The Heavenly Father is sitting on the throne of His glory, holding in His right hand the book sealed with seven seals. This is the mystery of God, God’s plan of salvation for all mankind (Revelation 5:2). Not one was found who could open the book. Then however, the Lamb of God, Jesus, was qualified to reveal and carry out God’s glorious plan. “Weep not: behold, the Lion of the tribe of Judah, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.” (Revelation 5:5).
We look forward to that time of Christ’s reign when “…the LORD’S house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.” (Isaiah 2:2)
