The Bible mentions two future resurrections. Revelation 20:1 refers to the first resurrection “Here we are in the first rebirth. The one who participates in the first resurrection is blessed and holy! It is impossible for them to die, but they will be priests of God and Christ for a thousand years, and they will reign with him ” (Revelation 20:5b-6). People who participated in the first resurrection will be resurrected before Christ’s 1,000-year reign known as the millennium. As described in 1 Thessalonians 4:13-18 (the “dead in Christ” and those who are alive at the rapture), this first resurrection includes the resurrected Christian martyrs from the end of the tribulation period (Revelation 20:4). In Revelation 20:12-13, the second resurrection is described. “Books were open in front of the throne, and I saw the dead both large and small standing before the throne. One more book was then flipped open: that of life. And the dead were judged based on their deeds as recorded in the scriptures. Death and Hades also expelled their residents, and each one was held accountable for the deeds they had committed while still alive.” People who reject God’s Word and are destined for the Lake of Fire include everyone who falls into this category (Revelation 20:15).
The 1,000-year millennial kingdom will take place in the interval between the two resurrections. At this time, believers are already resurrected and reign with Christ. “The rest of the dead did not come to life until the thousand years were over.”
That’s why there are two resurrections: one for God’s followers and one to judge the unbelieving. One’s relationship with God via Jesus Christ distinguishes these two groups. Anyone who desires a place in heaven must first hear the gospel and be saved by grace through faith (Ephesians 2:8–9). (John 3:16).
