Where does he indicate that?
Where are you getting that from? Don't just make claims without backing them up. Show the scripture that you are basing this claim on.
Did I not acknowledge that sin will no longer be present after Christ returns? Of course I acknowledge that. So, who are you directing your question towards?
"Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?"
Peter points out things are dissolved, not that heaven and earth have passed. The Day of God, comes after the Day of the Lord. Jesus Christ reigns until the end of the earthly kingdom.
"afterward they that are Christ's at his coming. Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power."
The end cometh after the Second Coming, not at the Second Coming. The verse says Christ brings those at the Second Coming, not that Christ is handing over the kingdom.
"For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God bring with him."
"afterward they that are Christ's at his coming."
The point is based on a resurrection, not necessarily a time of judgment. Paul is pointing out the process of giving God souls at three different points in time, not just 2.
"For as in Adam all die, even so in Christ shall all be made alive. But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming. Then cometh the end, when he shall have delivered up the kingdom to God,"
The Cross was the firstfruits, because Christ brings the firstfruits with Him at the Second Coming. The Second Coming is the second harvest. Then comes the end after the kingdom is handed to God. We have had 1991 years of Christ with the firstfruits, then Christ comes to earth as Prince, then the end comes 1000 years later, when the kingdom on earth is handed back to God.
The point is what was accomplished at each step. The physical resurrection was completed at the Cross. No need to go back to the physical aspect of Redemption. The Second Coming is the end of the spiritual aspect of life. The Spiritual kingdom is complete, and no need to go back to the spiritual aspect of Redemption. Now at the Second Coming we have a resurrection that is physical, and Jesus Christ will fulfill all the physical aspects of the iron rule.
We have not been under the iron rule, but under grace and accepting God by faith. The Millennium is not about faith or even the spiritual aspect of Redemption, because that all has been settled in the church. But Daniel 9, has not been lived out in reality on earth.
The Second Coming harvest also produces firstfruits, not for the church, but for the resurrection of Revelation 20:4. The Millennium is for these firstfruits, just like the church and the last 1991 years has been for the firstfruits of the first coming in the first century.
The OT saints have not been ever present on earth for the last 1991 years. In like manner the church will not be present on earth during the Millennium. Not, that they will not be reigning over the earth, not just on the earth. Have those in Paradise presided over the last 1991 years?
"Wherefore seeing we also are compassed about with so great a cloud of witnesses, let us lay aside every weight, and the sin which doth so easily beset us, and let us run with patience the race that is set before us,"
