The whole point & purpose of Peter's 1st recorded sermon, immediately after "Pentecost" is that Jesus IS the Messiah, Christ, Anointed One, Seed (son) of David, King of Israel, fulfillment of all prophetic scripture -- whom the Jews crucified. And according to Acts 2, Jesus, whom is the heir therefore, to the Davidic covenant, and throne -- is actually seated on that throne right now as we speak, reigning over all things, through, and on behalf of, His Church (Eph. 1). Emphasis in following Bible passages is mine.
Act 2:32 This Jesus hath God raised up, whereof we all are witnesses.
Act 2:33 Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.
Act 2:34 For David is not ascended into the heavens: but he saith himself, The LORD said unto my Lord, Sit thou on my right hand,
Act 2:35 Until I make thy foes thy footstool.
Act 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ.
Eph 1:17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him:
Eph 1:18 The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints,
Eph 1:19 And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power,
Eph 1:20 Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places,
Eph 1:21 Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come:
Eph 1:22 And hath put all things under his feet, and gave him to be the head over all things to the church,
Eph 1:23 Which is his body, the fulness of him that filleth all in all.
This 'reigning at the right hand of the Father' shall be, "Until I make thy foes thy footstool." Which thing David stated in Psalm 110:1. Where the King sits is his throne. Jesus is sitting and enthroned, at the right hand of the father. there is no higher or greater seat or throne to be had. A further study of all passages related to Christ's reigning at the right hand will corroborate these facts.
Now, if we take a look at 1 Cor. 15, the 'Rapture Chapter,' if you will, we find these interesting things:
1Co 15:22 For as in Adam all die, even so in Christ shall all be made alive.
1Co 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
1Co 15:24 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.
1Co 15:25 For he must reign, till he hath put all enemies under his feet.
1Co 15:26 The last enemy that shall be destroyed is death.
1Co 15:27 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.
1Co 15:28 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.
1Co 15:50 Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
1Co 15:51 Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed,
1Co 15:52 In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.
1Co 15:53 For this corruptible must put on incorruption, and this mortal must put on immortality.
1Co 15:54 So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
1Co 15:55 O death, where is thy sting? O grave, where is thy victory?
1Co 15:56 The sting of death is sin; and the strength of sin is the law.
1Co 15:57 But thanks be to God, which giveth us the victory through our Lord Jesus Christ.
So then, if there is a "great" tribulation to come, and there is, and if there is a millennial 'period' to occur, and there is -- then both MUST precede the 'rapture' and "the end" (1 Cor. 15:24), which are synonymous or parallel here.
This meshes perfectly with Jesus direct answer to His disciples direct question in Matthew 24:
Mat 24:3 And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?
Mat 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be.
Mat 24:22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
Mat 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Mat 24:31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Further corroboration can be provided for the soundness and consistency of this interpretation by looking at:
Heb 12:26 Whose voice then shook the earth: but now he hath promised, saying, Yet once more I shake not the earth only, but also heaven.
Heb 12:27 And this word, Yet once more, signifieth the removing of those things that are shaken, as of things that are made, that those things which cannot be shaken may remain.
This then, would again be "the end" of the world -- when all physical (made) things are removed. Also, compare the 7th seal and the 7th or "last trump" in Revelation, though admittedly a more complex study, it is none-the-less, perfectly consistent.
Clearly, this shows us that Christ is reigning, and will reign, on the Throne of David, at the right hand of the Father, until the last enemy (death) is made his footstool, which is accomplished at the 'Rapture,' which occurs at 'The End' of the world.
Though this is a brief & concise effort, if it still seems overwhelming, or a bit much to work through, perhaps this question will clarify or simplify, if not too much:
"How can flesh & blood, corruptible (subject to death & decay) beings be 'alive' on the earth, especially alongside incorruptible, changed, resurrected bodies (like unto Christ's resurrected body), AFTER 'death' is conquered and vanquished, which occurs at the rapture?"
Food for thought.
