When you say "destroyed" you mean cast into the lake of fire, right? If Premill was true, then obviously any believers who died during the thousand years would need to be resurrected after the thousand years, so I'm not sure why any Premill would believe otherwise.
No one dies during the Millennium. That is the whole point of them not being mortals. Mortals implies death. They are righteous and "shine as the sun" meaning there is no limit to their lives, period. When they have offspring, the offspring are not mortals either. There are no mortals born, period. If a young person decides to rebel, they are considered cursed and they are placed in Death, which is a location separate from life on earth. It is not rehab. It is not a prison. It is not being sent immediately through time to the GWT judgment. It is Death, which is dealt with at the GWT.
Like sheol since Adam's physical death, it is a place where the souls of those who rejected God wait for time to pass. That Death is the last enemy, not sheol. In Revelation 20:5 those dead are still waiting in sheol, like they have since before the Flood of Noah's day. They were not let out of sheol, at the Cross when those from Abraham's bosom were physically resurrected. Sheol was defeated at the Cross. That was the death defeated in the first century. Even Lazarus heard the voice of Jesus and came forth out of his grave. Are you going to say that Scripture contradicts John 5? Because the hour already was present when Lazarus came out of his grave? That is why Jesus said that hour was already here. Lazarus came forth. At the Cross all of Abraham's bosom came out of their graves physically. They are not waiting for some hour in the future, nor did the wicked come out either.
I know you apply that as strictly spiritual limiting the full affect of that resurrection. But when you receive your permanent incorruptible physical body, you will understand the full power of that resurrection. If you tell God, you will wait until the GWT to get that body, your longsuffering may be granted, or not.
You all limit Jesus as the Resurrection and the Life, because you demand that Jesus plays by your rules that all the dead are resurrected at the same hour. Your interpretation contradicts Scripture that states other times of resurrection. You reject the point, Jesus made:
"Verily, verily, I say unto you, The hour is coming,
and now is, when the dead shall hear the voice of the Son of God: and they that hear shall live."
This verse does not state a single hour for both the wicked and the righteous. In fact it states an ongoing physical resurrection, because after the Cross, all the redeemed no longer taste death. Leaving Adam's dead corruptible flesh is a resurrection into God's permanent incorruptible physical body. That was proven in Lazarus, and all in Abraham's bosom at the Cross. One who is born from above by the Holy Spirit, only is mortal in this body. They no longer have to walk through the valley of the shadow of death as did David and all in Abraham's bosom. Paradise was opened at the Cross, along with direct access to the Holy of Holies. You all know and quote the verses. You just follow Amil bias to interpret them.
