Because the words "we" and "sleep" in
1 Thessalonians 5:10 reveal that chapter 5 is connected to chapter 4. The timing of the event found at the end of chapter 4 occurs on "the day of the Lord", when He "comes as a thief" found at the beginning of chapter 5.
Your opinion, based on very flimsy evidence.
Revelation 16:16
The spirits assemble the armies at Armageddon.
[This is a wide valley, just northeast of Mt Carmel, actually quite a distance from Jerusalem – at least 2 days march, I would think.]
Is this event, at to the Return of Jesus, the same as the Lord’s Day of vengeance and wrath?
Purpose To destroy the armies attacking Jerusalem, not a judgement against the nations.
Location - This attack is just in Israel, not worldwide, as is the Day of vengeance and wrath.
The players- The Anti Christ, beast and false prophet are not mentioned at the Day of vengeance and wrath, the Sixth Seal and the many other prophesies of that event.
The method - Destruction by Christ’s sharp sword, not the same as the vivid descriptions of a fire judgement, prophesied more than 70 times in the Bible and referred to in Hebrews 10:27, 2 Thessalonians 1:7-8, 2 Peter 3:7.
It is evident that there are two separate ‘Days of the Lord’ in which the Lord acts to punish His enemies. The Sixth Seal,
the Day of the Lord’s vengeance and wrath, is the next prophesied event that we can expect, of a worldwide judgement/punishment by fire from the sun, which will clear and cleanse His Land. Most clearly described in Isaiah 63:1-6 and Habakkuk 3:12 ‘
Furiously You traverse the earth, in anger You trample down the nations.’ But the Lord is not seen: Psalms 11:4-6, Psalms 18:11
Then, much later, at the Return of Jesus, is the Sixth and Seventh Bowl fulfilment, the
great Day of the Sovereign Lord, when He disposes of the armies of the Anti Christ.
Revelation 19:19-21, Zechariah 14:3-5
On that glorious Day, Jesus' Return will not be unexpected, as a thief. Anyone who knows the bible will be aware that His Return will happen exactly 1260 days after the AC desecrates the Temple.
