The Purpose of the (literal) 1000 year reign is to fulfill The promises of Israel as a nation and restore her earthly glory among the nations under the rule of the son of David (Christ) (a perpetual promise). (2 Sam. 7:4-19) (Psalms 89:20-37) Study it, this is called the Davidic Covenant. (Psalms 89:34-35).
The popularity of the "literal" 1000 year reign is also a rather modern development which came along with the new doctrines of the "Rapture/dispensational" theology which arose in the 19th century.
The Church has had a very different view since it's beginning.
Prior to the 19th century, when John Darby et. al. made the dispensational teaching popular, with a very few exceptions, a literal understanding of the "1000 years" was rejected.
The number "1000" was understood to refer to a long time rather than a literal 1000 years.
Jesus declared himself to be ruler of everything in heaven and earth at Matthew 28:18. That means that He has been reigning from about 35 Ad until this minute.
1Co 15:25-26 For He must reign till He has put all enemies under His feet. The last enemy that will be destroyed is death.
Heb 10:12-13 But this Man, after He had offered one sacrifice for sins forever, sat down at the right hand of God, from that time waiting till His enemies are made His footstool.
And that He is personally present on the earth is established by the fact that the Church is His body which is present on the earth.
Col 1:18
And He is the head of the body, the church,
Col 1:24
I now rejoice in my sufferings for you, and fill up in my flesh what is lacking in the afflictions of Christ, for the sake of His body, which is the church,
So, if the Church is in the world and Christ is in the Church, then Jesus is personally present in the world over which He has been given all authority right now.
My understanding is that such things as "the rapture" and "the 1000 year reign" are of very minimal importance. At Mathew 24 and 25 Jesus made an extensive statement that "the times and the seasons" are not our concern but what we need to focus on being ready for His return so that we may hear Jesus say, "Come, you blessed of My Father, inherit the kingdom prepared for you from the foundation of the world" (v 34) and not "Depart from Me, you cursed, into the everlasting fire prepared for the devil and his angels" (v 41)
To me, the whole rapture, 1000 year reign, who, what , when, and where (according to the preacher's beautifully prepared power point presentation) is a distraction which tends to entice Christians to give more importance to things which are not our business rather than to things that ARE our business which is doing the good works "
For we are His workmanship, created in Christ Jesus ... which God prepared beforehand that we should walk in them." (Eph 2:10) and letting our "
...light so shine before men, that they may see your good works and glorify your Father in heaven." (Mat 5:16)
When Jesus comes, He is not going to judge according to whether we knew when the "rapture" was going to happen or when the "1000 year reign" would begin>
He won't judge mankind based on what we know.
He will judge all of mankind based on what we did or did not do.
(Mat 25:31-46; Jhn 3:36; 5:28-29; 8:51; Ro 6:2-10; 8:12-14; 2Cor 5:10; 1 Pet 1:17; 1 John 2:17; Rev 20:12-13; 22:12-14)
I suggest that we devote our time to doing Jesus' will rather than spending our time studying the innovative theology of John Darby et. al. lest we come before the Master and say, "Here's the talent you gave me. I buried it but didn't earn anything more with it."
but, as you know, that's just me
