At present, JW believe that Jesus began ruling in 1914. However, the millennium starts after Armageddon. I don’t know how Revelation is going to play out exactly.
Fisherman, technically the millennium can't start AFTER Armageddon but instead starts at Armageddon, The reason being is because ALL the chosen have to be with Jesus when Armageddon commences, and in order for ALL chosen to be with Jesus at that time, the 'first resurrection' would have to have occurred. In order for the 'first resurrection' to occur the 'last day' has to come and the 'last trumpet' has to sound.
When Jesus comes AFTER the GT is when his chosen are gathered together to him. This coming will be on the 'last day', which is a 1,000 yearlong day. The chosen are resurrected at the time he comes. Look at the following and tell me if you agree or where you disagree:
[John
11:24 “I know he will rise in the resurrection on the last day.”]
[John 6:39 This is the will of him who sent
me, that I should lose none out of all those whom he has given me, but that
I should resurrect them on the last day.]
[Rev 20:6 Happy and holy is anyone having part
in the first resurrection; over these the second death has no
authority, but they will be priests of God and of the Christ, and they will
rule as kings with him for the 1,000 years.]
[2 Peter 3:8 But do not forget this one thing, dear friends: With the Lord a day is
like a thousand years, and a thousand years are like a day.]
[1 Thessalonians 4:15-17 By the word of the
Lord, we declare to you that we who are alive and remain until the
coming/presence of the Lord will by no means precede those who have
fallen asleep. For the Lord himself will descend from heaven with
a commanding call, with an archangel’s voice and with God’s
trumpet, and those who are dead in union with Christ will rise
first. Then we the living who are surviving will, at the same time
with them, be caught away in clouds to meet the Lord in the air;
and thus we shall always be with the Lord.]
[1 Corinthians 15:52 in the twinkling of an
eye, at the last trumpet. For the trumpet will sound, and
the dead will be raised up incorruptible, and we shall be changed.]
[Matthew 24: 29 “Immediately after the
tribulation of those days the sun will be darkened, and the moon will
not give its light, and the stars will fall from heaven, and the powers of the
heavens will be shaken. 30 And then the sign of the Son of man will appear in
heaven, and then all the tribes of the earth will beat themselves in
lamentation, and they will see the Son of man coming on the clouds of
heaven with power and great glory. 31 And he will send forth his
angels with a great trumpet sound, and they will gather his
chosen ones together from the four winds, from one extremity of the
heavens to their other extremity.]
[2 Thessalonians 2:1 Concerning the
coming/presence of our Lord Jesus Christ and our being gathered to him, we
ask you, brothers and sisters,]
[2-15-86 WT p.19 par.14 – It is understood that anointed Christians sleeping in death are raised at the sounding of “the last trumpet,” which takes place during the “manifestation” of Jesus Christ in Kingdom glory. (1 Corinthians 15:52; 2 Timothy 4:1, 8)]
[5-1-90 WT p.26 par.9 – Martha knew about that hope from her association with Jesus, for she had previously said to him regarding Lazarus: “I know he will rise in the resurrection on the last day.” (John 11:24) She knew that the resurrection would be, not on his (Lazarus’) last day, but in the future, “on the last day”—Judgment Day, when the dead would be raised under God’s Kingdom rule.]
[Insight Vol 2 – Because of having been resurrected by his friend Jesus, Lazarus was likely alive Pentecost 33 C.E., when the holy spirit was poured out and the first ones of the heavenly calling (Heb 3:1) were anointed and spirit begotten. (Ac 2:1-4, 33, 38)]
[12-1-89 WT p.9 – The judgment will take place “in the last day,” during Christ’s Thousand Year Reign.]
[4-1-82 WT p.23 par.13 – Consequently, the expression “come to life” must refer to the situation at the end of the 1,000-year-long Judgment Day.]
[7-1-98 WT p.21 par.12 – That “last day” coincides with the Thousand Year Reign of Christ. (Revelation 20:6) Imagine the excitement during that “day” when this grand event begins!]
