When Will Everyone Be Resurrected?

 While lots of Christian churches may teach differently about the resurrection of the dead, they ALL have to be in agreement that there WILL be a resurrection of the dead.  We all say it in the Apostle's Creed, so it's part of the Christian faith just like Jesus died and was resurrected is part of the faith.

Here's the simple answer and then I will give you some links from a source I trust.

Jesus was the first resurrection.  He was the "first fruits" and an example of what believers will eventually become.

The next resurrection will happen at the rapture.  All believers from the Day of Pentecost until the trumpet sounds announcing the rapture who have died will be resurrected and given new bodies.  Those of us who are still alive will then be transformed into our new bodies in the twinkling of an eye and together we will all meet Jesus in the air.

Next up will be when Jesus returns to earth to establish his 1000 year reign and sit on David's throne in Jerusalem.  At this point all the people who died having faith in Jesus during the Great Tribulation will be resurrected to rule and reign with Christ for 1000 years.  This is also the time that all the OT saints like Noah, David, John the Baptist, etc... will also be resurrected and given new bodies.

At the end of the 1000 years all the unbelievers throughout all of time will be resurrected and stand at the Great White Throne judgment.  They will bow to Jesus, some will try and convince him that they knew him, but Jesus will sentence them all to eternal damnation at this judgment.

This really only leaves one group to be resurrected.  This would be the people who survived the Great Tribulation as humans and entered into the 1000 years in their human bodies.  They and their kids, grandkids, and all their great, great, great grandkids will still have human bodies throughout the 1000 years.  The Bible doesn't speak specifically as to WHEN they will get their new bodies so that they can inhabit eternity, but some evidence would point to this happening at the end of the 1000 years.  At the end of the 1000 years God is going to burn the entire earth and make a new heavens and a new earth so they will need to have their eternal bodies at this point.

The first great resurrection was the resurrection of Jesus Christ. It is documented in each of the four Gospels (Matthew 28; Mark 16; Luke 24; John 20), cited several times in Acts (Acts 1:22; 2:31; 4:2, 33; 26:23), and mentioned repeatedly in the letters to the churches (Romans 1:4; Philippians 3:10; 1 Peter 1:3). Much is made of the importance of Christ’s resurrection in 1 Corinthians 15:12-34, which records that over five hundred people saw Him at one of His post-resurrection appearances. Christ’s resurrection is the “first fruits” or guarantee to every Christian that he will also be resurrected. Christ’s resurrection is also the basis of the Christian’s certainty that all people who have died will one day be raised to face fair and even-handed judgment by Jesus Christ (Acts 17:30-31). The resurrection to eternal life is described as “the first resurrection” (Revelation 20:5-6); the resurrection to judgment and torment is described as “the second death” (Revelation 20:6, 13-15).

The first great resurrection of the Church will occur at the time of the rapture. All those who have placed their trust in Jesus Christ during the Church Age, and have died before Jesus returns, will be resurrected at the rapture. The Church Age began on the Day of Pentecost and will end when Christ returns to take believers back to heaven with Him (John 14:1-3; 1 Thessalonians 4:16-17). The Apostle Paul explained that not all Christians will die, but all will be changed, i.e., given resurrection-type bodies (1 Corinthians 15:50-58), some without having to die! Christians who are alive, and those who have already died, will be caught up to meet the Lord in the air and be with Him always!

Another great resurrection will occur when Christ returns to earth (His Second Coming) at the end of the Tribulation period. After the rapture, the Tribulation is the next event after the Church Age in God’s chronology. This will be a time of terrible judgment upon the world, described in great detail in Revelation chapters 6-18. Though all Church Age believers will be gone, millions of people left behind on earth will come to their senses during this time and will trust in Jesus as their Savior. Tragically, most of them will pay for their faith in Jesus by losing their lives (Revelation 6:9-11; 7:9-17; 13:7, 15-17; 17:6; 19:1-2). These believers in Jesus who die during the Tribulation will be resurrected at Christ’s return and will reign with Him for a thousand years during the Millennium (Revelation 20:4, 6). Old Testament believers such as Job, Noah, Abraham, David and even John the Baptist (who was assassinated before the Church began) will be resurrected at this time also. Several passages in the Old Testament mention this event (Job 19:25-27; Isaiah 26:19; Daniel 12:1-2; Hosea 13:14). Ezekiel 37:1-14 describes primarily the regathering of the Nation of Israel using the symbolism of dead corpses coming back to life. But from the language used, a physical resurrection of dead Israelis cannot be excluded from the passage. Again, all believers in God (in the Old Testament era) and all believers in Jesus (in the New Testament era) participate in the first resurrection, a resurrection to life (Revelation 20:4, 6).

So there will not be ONE resurrection but many.  But one thing is for sure, EVERYONE WILL BE resurrected at some point.
