You are seeing things! Where is your so-called future millennium mentioned there? Read the text. The end comes at the second coming. There is no space for time and continued sin and sinners. You force it into the next, as usual.
Who said anything about sin and sinners?
Paul gives us an order. You strictly deny any order at all. You outright reject Paul's order, and claim a single point of time the redeemed are collected.
You literally leave all those is Abraham's bosom until a last day in the future. That is futurism. You teach all souls currently go to Abraham's bosom, and that is Judaism.
You are stuck in a recap that has to be taught, and you have no resemblance of Paul's teachings in your posted statement of belief.
You deny the first resurrection is physical, and call the second birth this alleged, in your terms, a first "spiritual" resurrection, but yet leave all souls in Abraham's bosom, because you reject the order Paul gives.
The firstfruits are the first physical resurrection of those souls in Abraham's bosom. They have permanent incorruptible physical bodies in Paradise.
The Second Coming allows those alive in Adam's dead corruptible flesh to receive the first resurrection into permanent incorruptible physical bodies.
At the end, those who lived for those 1,000 years after the Second Coming already have permanent incorruptible physical bodies. They are presented to God with the rest of creation without spot or blemish.
3 orders of presentation, by Christ to God.
You read the text: "then comes the end." It does not define the Second Coming as the end. The end is defined by the rule of Christ as King after the Second Coming. Jesus has reigned eternal since He created the heavens and earth. The last 1,000 years are on earth, even though most of the church may reject that point. Jesus reigned while souls were in Abraham's bosom. Jesus has reigned since presenting those souls from Abraham's bosom to God, and giving them a first resurrection, into permanent incorruptible physical bodies. Jesus will reign on earth after the Second Coming, because the whole point of the Second Coming is to finish the King part of the promised Messiah the Prince given to Daniel's people.
Christ was cut off for the fulness of the Gentiles. Daniel 9:26
"And after threescore and two weeks shall Messiah be cut off, but not for himself:"
Are you going to deny this is for the fulness of the Gentiles, because it is not explicitly stated in this verse? You seem to base most of your Amil position on verses that do not even specifically state your position. Now you deny the very reason in this verse, that Jesus was not made King at the time He was the Christ.
You claim He was physically Messiah on earth, and then deny He will be physically Prince on earth as well. When we know full well He was cut off, not for an earthly ministry, but for the fulness of the Gentiles, until He comes the Second time without sin, for a holy and righteous kingdom that is with observation. Creation is handed back whole, 1,000 years after sin and Satan are removed.
