The Seventh Trumpet, Revelation Chapter 11 Verses 15-19 (NASB)

    And the SEVENTH angel sounded;
This is the last "trumpet" judgment (Revelation 8:2,6). It coincides with the third woe (verse 14) and contains the portion (Revelation 11:16 - Revelation 19:11) with the seven bowls.
    and there arose loud voices in heaven, saying,
Not clear if these are angelic or saintly or both. There is no context here other than the previous announcements (Revelation 10:1,3) were by a strong angel with a loud voice.
Kingdom(s) are what Satan offered Jesus at temptation time (Luke 4:1-13). Satan even admitted 'they were handed over to him' so he got them from somoone else. Now that SOMEONE has acquired the 'Kingdom of the World' again. The world has to be reacquired from the devil such that he will not have any authority there when he is kicked out of heaven (Revelation 12:9).
    and He will reign FOREVER AND EVER."
There will not be a possibility that another "fallen angel" will acquire the Kingdom of the World. This is a FINAL solution; the end of Satan's rule. The interpretation of Daniel to a worldly king's dream (Daniel 2:36-44-45) indicates after this king there would be other kingdoms, and then a FOREVER kingdom. Psalm 2:1-6, Psalm 45:6-9, and Revelation 19:6 talk about this 'FOREVER and EVER' kingdom.
    And the twenty-four ELDERS, who sit on their thrones BEFORE GOD,
Immediately after John's invitation into heaven (Revelation 4:1), we see the THRONES and ELDERS (Revelation 4:4). At that time before the 'seal judgments', they had fallen down and worshiped (Revelation 5:8).

This is the last reference in the Revelation to the 24 THRONES. They have been made unnecessary by the establishment of the kingdom of our Lord. Later, in Revelation 19:4, we see the ELDERS falling down and worshipping God again, but there is no mention of the THRONES.

Notice that the focus of attention is BEFORE GOD. This is what God demands: that we do all BEFORE HIM!

    fell on their faces and worshiped God,
This is the whole consuming activity of 'redeemed men' as represented by the 24 ELDERS. The apostile Paul refers to 'redeemed' as the true circumcision who worship in the Spirit of God and glory in Christ Jesus (Philippians 3:3). On earth, we have the Holy Spirit and the glory of Christ; in heaven, we worship GOD!

Notice that the tense of the verb in Revelation 4:10 is "will worship"; here, it is "worshiped" (past active) meaning it started in the past and is ongoing.

Lastly, the act of worship here in the Revelation is face downward in complete subjection and humility. This is the opposite of the way many Pentacostal churches today conduct "Praise and Worship" with hands raised and faces looking upward. This may be the difference of how it is in the 'kingdom of the world' in which we are now and the 'kingdom of the Lord' in the future. It is curious that we don't practice worship today as it will be done in the 'kingdom of our Lord'.
     "We give Thee Thanks,
All our worship of God should begin with THANKS.
    O Lord God, the Almighty,
This is the fullest, most majestic title of God. There is no doubt to WHOM this thanksgiving is directed. Recall that Satan wanted Jesus to WORSHIP him in Luke 4:7. In return, Satan would give Jesus the kingdoms of the earth (now belongs to Christ, verse 15). How wrong Satan was!
    who ART and who WAST,
King James Version adds 'who art to come'. BUT He has come and
    because Thou hast taken Thy great POWER
This is the same POWER that was promised to us in Acts 1:6-11.
    and hast begun to REIGN.
There is a time (we are living in it now), where Satan is permitted to REIGN or be ruler over the earth. During this period, Jesus' wish is that none should perish (2 Peter 3:9), but with the seventh trumpet (third woe), the time for repentence is over. Christ has begun to REIGN. The STONE of Daniel 2:31-35 and Daniel 2:40-44-45 is in the process of crushing kingdoms. It takes GREAT POWER to accomplish this (Luke 12:5). Jesus prayed that this POWER to REIGN would be given to His disciples, John 17:6-18-19.
    "And the NATIONS were enraged,
The devil knows by the time the seventh trumpet is sounded that he only has a short time to subvert the world (NATIONS). Inasmuch the NATIONS are enraged, it shows the effectiveness of the devil. But this should be no surprise. Even the psalmist writes of the uproar of the nations, Psalm 2:1-3.
    and THY WRATH came
This is judgment time:
Revelation 14:7 Fear the Creator
Revelation 16:1 Seven bowls of wrath
Revelation 18:20 Babylon's judgment
Revelation 19:19b Beast and kings of the earth are against Christ - Armaggedon
Revelation 20:11-15 Great White Throne judgment

There are three 'times' now:
  1. the time came for the dead to be judged, and
    Daniel sees this in Daniel 12:2-3.
  2. the time to give their REWARD
    This "reward giving" is probably different than translated believers (Revelation 4:1), who are investigated (Revelation 4:2), coronated (Revelation 4:4) and then returned the crowns to Jesus' feet (Revelation 4:10-11). Note who receives this reward:
  3. and {the time came} to DESTROY those who destroy the earth." Remember that the earth is the Lord's, Genesis 1:1 and Exodus 9:29. Yet mankind in our sinful state has systemically destroyed God's creation. Even so called Christians often don't respect what God made. They litter, use chemicals, and misuse water sources.

    From a figurative view, it is deception which is destroying the earth. It is carried out by the beast, dragon, and false prophets who perform signs to confirm their deception (Revelation 19:20, Revelation 20:1ff, and Revelation 16:13ff)

    And the temple of God which is in heaven was opened;
The Revelation of Jesus Christ is an "opening" book:

Door opened Revelation 4:1
Seals opened Revelation 6:1-9
Abyss opened Revelation 9:2
Heaven opened Revelation 19:11
The books opened Revelation 20:12
What has been hidden from us and the earth in the spiritual realm is slowly revealed. With the revelation comes an awareness of God's purity and holiness. The result of the encounter with purity and holiness is judgment against sin and the devil (Revelation chapters 12-16).

Since the temple is the place of worship, this encounter is a worshipful experience. John saw parts of this temple previously: throne and sea of glass (Revelation 4:6); and altar (Revelation 6:9, Revelation 8:3-5); and service by tribulation saints (Revelation 7:15).

Isaiah saw the throne and temple in Isaiah 6:1. Paul indicates this temple is where Christ now is ministering as High Priest (Hebrews 8:1-7). Recall, Christ as the untimate sacrifice is able to be this High Priest, Hebrews 9:23-26.

    and the ark of His covenant appeared in His temple;
The ark with its mercy seat (Exodus 37:1-9) speaks to atonement for sin. Thus this typifies Christ; the law, manna, and Aaron's rod contained therein show man's dependence/imperfection with respect to God.

In the Old Testament, the last reference to the ark occurs in 2 Chronicles 8:11. Later, Solomon with his involvment with Pharoah's daughter, Queen Sheba (Ethiopian), gave "all her desire (2 Chronicles 9:12) including perhaps the Ark. Ethiopian history claims the Ark is guarded in a church in Aksum, Ethiopia.

Isaiah has a prophesy in Isaiah 18:1-7 which may indicate the return of the ark. The 'standard' in verse 3 (nes in Hebrew) could be translated as 'ark'. Likewise, the 'gift' (nes, again) in verse 7 is returned 'to the place of the name of the Lord of hosts'.

    and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm.
Compare this to events at the temple at Christ's death, Matthew 27:51.
