When the seventh trumpet sounds, John hears loud voices in heaven declaring the kingdom of the world has become the kingdom of the Lord and his Messiah (Christ), and the Lord’s messiah will “forever and ever.”
Revelation 11:15 states the kingdom “has come.” Aune says this aorist middle verb (ἐγγένετο, from γίνομαι) functions like a prophetic perfect. The verb “has come” is referring to something that has not happened yet but is so certain it can be spoken of as if it had already happened (Aune 2:638). Wallace would call this a proleptic aorist (GGBB 563). As an analogy, your mother announces, “it is time to eat thanksgiving dinner,” but there are several things that happen before you are sitting at the table eating the meal.
This kingdom belongs to “our Lord and of his Christ.” This is a clear statement the real Lord of this world is God, not any human who claims to be lord of this world. This anticipates the increasingly anti-Roman rhetoric beginning with the two beasts in Revelation 13 and culminating in the great whore of Babylon.
The messiah will rule the Lord’s kingdom. Although the word Χριστός is usually translated Christ, it is important to remember the word translates the Hebrew word usually translated messiah or “anointed one.” For example, in the Septuagint, the Lord’s anointed in Psalm 2:2 is מָשִׁיחַ , (māšîaḥ) is translated as Χριστός, a text applied to Jesus in Acts 4:26). This anointed one may be the king of Israel (David, 2 Sam 22:51) or some person chosen by God for a task (Cyrus the Persian, Isaiah 45:1). By the Second Temple Period, the messiah/Christ was used for the coming representative of God who would restore Israel. For example, Psalm of Solomon 18:6, “May God cleanse Israel for the day of mercy with blessing, for the day of election ⌊when he brings up⌋ his anointed one (LES2). In the Odes of Solomon 29:6-11, the writer believes in the “Lord’s Messiah” and considered him to be the Lord. This messiah will “subdue the thoughts of the gentiles and humble the strength of the mighty.”
This messiah will rule forever (εἰς τοὺς αἰῶνας τῶν αἰώνων). This is likely an allusion to Daniel 7:14, but the idea God’s kingdom will never end is found elsewhere (Ps 146:10). In the Second Temple period book the Wisdom of Solomon, the righteous will “govern nations and rule over peoples, and the Lord will reign over them forever” (3:8, NRSV). In Joseph and Asenath “the Lord God will reign as king over them for ever and ever” (19:8).
The jubilation of the seventh trumpet stands in contrast to the seventh seal, silence in heaven for about a half hour. I suggested in an earlier post this silence is a form of worship, so the silence of the seventh seal answered by the noisy worship of the twenty-four elders. The seventh seal, trumpet and bowl each refer to the coming of the messiah, the defeat of the kingdom of man, and the beginning of the Kingdom of God.
