You are adding to scripture. It does not say anything Christ playing politics in the flesh for 1,000 years.
The chaining up of Satan is a symbol for Christ’s resurrection-victory over death and the forces of evil.
But God, who is rich in mercy, because of the great love he had for us, even when we were dead in our transgressions, brought us to life with Christ (by grace you have been saved), raised us up with him, and seated us with him in the heavens in Christ Jesus, that in the ages to come he might show the immeasurable riches of his grace in his kindness to us in Christ Jesus. (Eph 2:4-7)
If then you were raised with Christ, seek what is above, where Christ is seated at the right hand of God. Think of what is above, not of what is on earth. For you have died, and your life is hidden with Christ in God. When Christ your life appears, then you too will appear with him in glory. (Col 3:1-4)
We have already risen with Christ by virtue of the Holy Spirit, but this remains hidden with Christ until we go there at the end of our life. That is the first resurrection. The second resurrection happens at the end.
But our citizenship is in heaven, and from it we also await a savior, the Lord Jesus Christ. He will change our lowly body to conform with his glorified body by the power that enables him also to bring all things into subjection to himself. (Phil 3:20-21)
For just as in Adam all die, so too in Christ shall all be brought to life, but each one in proper order: Christ the firstfruits; then, at his coming, those who belong to Christ; then comes the end, when he hands over the kingdom to his God and Father, when he has destroyed every sovereignty and every authority and power. For he must reign until he has put all his enemies under his feet. (1 Cor 15:22-25)
There is no mention of a 1,000 year literal reign because he has been reigning for two millenia. Reigning is about dealing with enemies now. He will finish them off when he returns. There is an immediate end.
This is when Christ appears.
**For the Lord himself, with a word of command, with the voice of an archangel and with the trumpet of God, will come down from heaven, and the dead in Christ will rise first. Then we who are alive, who are left, will be caught up together with them in the clouds to meet the Lord in the air. Thus we shall always be with the Lord. (1 Thes 4:16-17)
"When the Son of Man comes in his glory, and all the angels with him, he will sit upon his glorious throne, and all the nations will be assembled before him. And he will separate them one from another, as a shepherd separates the sheep from the goats. He will place the sheep on his right and the goats on his left. (Mat 25:31-33)**
The second resurrection is at the end of time and that is the physical one.
