The resurrection is not a future event. It marked the time of judgment, the end of the Old Covenant age, and the destruction of Jerusalem in 70 AD. Here's how scripture proves it:

• 1 Thessalonians 5:9 Paul said "us," meaning the Thessalonians. He was writing to "them," not us.
  
  

• Revelation 3:10 The word "world" is oikoumene (Strong's #3625), which referred to the Roman world of their time. John told "them" there would be no more delay (Revelation 10:6) and what must soon happen (Revelation 1:1-3).
  
  

• Matthew 24:29 "Sun, moon, and stars" is apocalyptic language.
  
  

  • Isaiah 13:1, 6, 10-11 used this language for Babylon's fall in 539 BC.
    
    

  • The lights in the sky were not literally darkened.
    
    

  • Jesus applied this to Jerusalem's judgment in "that generation" (Matthew 24:34, Luke 21:20-22).
    
    

• 1 Corinthians 15 and Isaiah 27:9-13 Paul tied the resurrection to Jerusalem's destruction.
  
  

  • The "last trumpet" is the seventh trumpet.
    
    

  • It marked the desolation of the city and destruction of the altar.
    
    

  • Paul said "they" were at the end of the ages (1 Corinthians 10:11).
    
    

  • "The world is passing away" (1 Corinthians 7:31), referring to the Old Covenant system.
    
    

• Daniel 12:2, 4, 7 and Daniel 9:24-27
  
  

  • The resurrection and "time of the end" happened when the power of the holy people (the Old Covenant system) was shattered.
    
    

  • That happened when the city and sanctuary were destroyed in 70 AD.
    
    

• Isaiah 25:2, 8
  
  

  • The resurrection is again linked to the destruction of the city.
    
    

• Revelation 11
  
  

  • "The city where the Lord was crucified" is Jerusalem (Revelation 11:8).
    
    

  • Revelation 11:15 declares Christ's kingdom came when Jerusalem (Babylon) was judged.
    
    

  • Jesus said "they" would see armies surround Jerusalem (Luke 21:20-22).
    
    

Oikoumene was their world. The time statements were literal. The resurrection, judgment, and end of the age were fulfilled in their generation.
