The Seventh Trumpet
Rev 11:15 And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
The seventh trumpet sounds announcing the soon triumphant return of the Lord Jesus Christ, to rule over the nations. His rule is everlasting.
Psa 146:10 The LORD shall reign for ever, even thy God, O Zion, unto all generations. Praise ye the LORD.
Rev 11:16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
Rev 11:17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
At last the beginning of the everlasting reign of God. His Son will return to earth for a thousand years to rule over the nations.
Rev 11:18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
The end is near. At the end of the thousand year reign would be the judgment of the wicked. Rewards would be given by Jesus to his faithful, they shall not see the wrath of God. The wicked would be eternally separated from God and heaven; no more sin, no more death.
Rev 11:19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.
The ark of his testament is in the heavenly temple, representing God's faithfulness. Here is a revelation and a view into heaven not previously seen. With the event there were lightenings and voices. On earth there were, or will be, thunderings and an earthquake, and great hail, perhaps such as occurred with Moses on Mt. Sinai at the giving of the law. Now it is God's grace we celebrate.
Exo 19:16 And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled.
We fear God in love, not fearing judgment, but respecting His power and Glory. He created us and all there is from nothing; now that really is something to praise him for.
