Millennial Reign of Christ

Finally, be strong in the Lord and in the strength of His might. Put on the full armor of God, so that you will be able to stand firm against the schemes of the devil. For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places. Therefore, take up the full armor of God, so that you will be able to resist in the evil day, and having done everything, to stand firm. - Ephesians 6:10-13 NASU

"Many nations will join themselves to the Lord in that day and will become My people. Then I will dwell in your midst, and you will know that the Lord of hosts has sent Me to you. - Zechariah 2:11 NASU

"But when the Son of Man comes in His glory, and all the angels with Him, then He will sit on His glorious throne.  "All the nations will be gathered before Him; and He will separate them from one another, as the shepherd separates the sheep from the goats;  and He will put the sheep on His right, and the goats on the left. - Matthew 25:31-33  NASU
