Look, it's really quite simple. One absolutely MUST have a good view of what to expect in the Millennium. It's NOT going to be the "time of peace" that everyone is expecting. It IS characterized by that "rod of iron":
1 Why do the heathen rage, and the people imagine a vain thing?
2 The kings of the earth set themselves, and the rulers take counsel together, against the LORD (YHWH), and against his Anointed, saying,
3 "Let us break their bands asunder, and cast away their cords from us."
4 He that sitteth in the heavens shall laugh: the Lord (Adonai) shall have them in derision.
5 Then shall he speak unto them in his wrath, and vex them in his sore displeasure.
6 "Yet have I set my king upon my holy hill of Zion.
7 I will declare the decree: 'the LORD (YHWH) hath said unto me, <<Thou art my Son; this day have I begotten thee.
8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.
9 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter's vessel.>>'
10 Be wise now therefore, O ye kings: be instructed, ye judges of the earth.
11 Serve the LORD (YHWH) with fear, and rejoice with trembling!
12 Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him!"
KJV (God the Father in both shades of purple, the Son of God in red.)
1 Corinthians 15:20-28
20 But now is Christ risen from the dead, and become the firstfruits of them that slept.
21 For since by man came death, by man came also the resurrection of the dead.
22 For as in Adam all die, even so in Christ shall all be made alive.
23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
24 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.
25 For he must reign, till he hath put all enemies under his feet.
26 The last enemy that shall be destroyed is death.
27 For he hath put all things under his feet. But when he saith, all things are put under him, it is manifest that he is excepted, which did put all things under him.
28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
Remember that 1 Cor. 15:20-28 is part of Paul's treatise on the resurrection. Therefore, his emphasis is not on the timing of the events but on the order of the recipients of the various resurrections. Just the same, the order is decipherable:
1. The Messiah (Christ) Himself was the firstfruits of the resurrection in the first century.
2. The next group that will be resurrected are His own when He comes again.
3. The final group to be resurrected will be resurrected at the end, which is when He will deliver up the Kingdom to God His Father.
This tells us that His Kingdom begins when He comes again and will last at least until He delivers up the Kingdom to God His Father. During the time that He is reigning, He will be putting down all rule and all authority and all power. THIS is what is going on during His Kingdom! When He has subdued everyone else, the last thing that He subdues is death itself. This corresponds to the Great White Throne Judgment (GWTJ) in Revelation 20:7-15, particularly verse 14.
(Actually, we learn from Gavri'el [Gabriel] in Luke 1:30-33 that Yeshua` will reign over the house of Ya`aqov [Jacob] forever.)
Therefore, the Millennium will be a time of the Messiah's great conquest as He becomes the "King of kings and Lord of lords," the world Emperor. The "time of peace" doesn't begin until God the Father is reigning forever after the creation of the New Heaven (the New Sky) and the New Earth. That doesn't occur until Revelation 21:1, AFTER the GWTJ. In this passage within 1 Corinthians 15, it doesn't begin until the Son has made Himself subject to God His Father and God the Father becomes "all in all."
Furthermore, one of the WORST mistakes that preachers today make is to suggest that the parables of Matthew 13 are about this current "church age." They are NOT! They are about the KINGDOM, which doesn't begin until the Messiah returns. Therefore, most of these parables (with the exception of the first parable) are about the time AFTER the Messiah returns and before He hands the Kingdom over to His Father. Consider the parable of the wheat and the tares, for example:
Matthew 13:24-30, 36-43
24 Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field:
25 But while men slept, his enemy came and sowed tares among the wheat, and went his way.
26 But when the blade was sprung up, and brought forth fruit, then appeared the tares also.
27 So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in thy field? from whence then hath it tares?
28 He said unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up?
29 But he said, Nay; lest while ye gather up the tares, ye root up also the wheat with them.
30 Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them in bundles to burn them: but gather the wheat into my barn.
36 Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field.
37 He answered and said unto them, He that soweth the good seed is the Son of man;
38 The field is the world (Greek: kosmos = the whole "world-system," not the "earth"); the good seed are the children of the kingdom; but the tares are the children of the wicked one;
39 The enemy that sowed them is the devil; the harvest is the end of the world (Greek: aioonos = age); and the reapers are the angels.
40 As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world (Greek: aioonos = age).
41 The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;
42 And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth.
43 Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear.
So, Yeshua` explains several of the elements of this parable explicitly:
He that soweth the good seed = the Son of man (Yeshua` the Messiah Himself);
The field = the world (Greek: kosmos = the whole "world-system," not the "earth");
The good seed = the children of the kingdom;
The tares = the children of the wicked one;
The enemy that sowed them = the devil;
The harvest = the end of the world (Greek: aioonos = age); and
The reapers = the angels.
Notice that it is not until the END of the age (the current age sandwiched between the Flood and the Fire, 2 Peter 3:3-13), the Millennium being the last 1,000 years of that age, that the "tares" are gathered out of the Messiah's Kingdom and burned. This also corresponds to the GWTJ. Afterward, the "wheat" are gathered into the "barn" of their Father's Kingdom, and this portion corresponds to the New Heaven (the New Sky) and the New Earth (the New Ground) of Revelation 21. (The "barn" could even represent the New Jerusalem. Not saying that it DOES, only that it COULD.)
