I agree with much of what you say as per scriptures and the Lord being both human and divine. Now just a couple of points.
You say that Christ `ASSUMED` the Father`s throne. The word `assumed,` can mean to usurp, to take for granted, to be arrogant. And obviously the Lord did not assume the Father`s throne in that sense.
Then the word `assumed` can also mean `to take or begin to have power or responsibility. So I think you mean that.
So we know that the Lord is sitting at the Father`s right hand till His enemies are brought to His footstool for judgment.
`The Lord (Father) said to my Lord (Son), "Sit at my right hand till I make your enemies your footstool." (Ps. 110: 1)
And what is the Lord doing at the Father`s right hand? He said " I will build my `called out ones.` (Matt. 16: 18) The details of that building is in Eph. 4: 11 - 16, Col. 2: 18 & 19.
So when the Lord`s enemies are brought to the Lord for judgment, what happens then? We know from God`s word that the Lord will begin to reign over those nations bringing judgments and putting down all rule and authority. When that is complete then the Son will subject Himself to the Father.
`...when He puts an end to all rule and authority .....when all things are made subject to Him, then the Son Himself will also be subject to Him who put all things under Him, that God may be all in all.` (1 Cor. 15: 24 & 28)
Thus we see that the Lord is on the Father`s throne and the Father will always have that throne. Then we also see that the Lord has authority over ever rule and authority in every realm. So where does the Lord exercise His great authority that the Father has given Him?
On the Father`s throne? I don`t believe so.
I believe that the Father has set up His Son`s own throne in another area. So where does God`s word tell us the Son`s `OWN THRONE` will be?
`To Him who overcomes I will grant to sit with Me on MY THRONE, as I also overcame and sat down with my Father on HIS THRONE.` (Rev. 3: 21)
Christ`s OWN THRONE is revealed in Ps. 2. The Father says -
`... I have set my King on my holy hill of Zion.` (Ps. 2: 6)
And where is that?
`But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, to an innumerable company of angels, to the General Assembly and church of the first-born who are registered in heaven, to God the judge of all, to the spirits of just men made perfect, to Jesus...` (Heb. 12: 22 - 24)
So we see that the Lord`s own throne will be in the highest realm of God`s great Kingdom where He will rule over every authority in every realm.
1. The Body of Christ with the Lord on His own throne. (Rev. 3: 21)
2. The OT saints in the New Jerusalem. (Heb. 11: 16)
3. Israel over the nations of the earth. (Rev. 21: 24, Isa. 66: 22)
The old covenant is gone forever. Israel lost her theology forever and her place of special favor. There will be no return to the same. The nations today are the focus of God's favor, not one small lone Christ-rejecting nation.
Premils are faced with an insurmountable obstacle here: Scripture only recognizes time up until Christ’s coming, and then eternity after this. There is no space or opportunity for the semi-glorious/semi-corrupt bipolar age that they anticipate. The age to come has eternity written all over it. It is not temporal. It is not sinful. It does not involve earthly sensual pleasures.
Where is this so-called future thousand years in 1 Corinthians 15:22-28? Nowhere! With you fixation of this supposed period, you force it into text after text where it does not belong.
1 Corinthians 15:22-28 outlines the climactic reality of Christ's coming and the fact it is "the end." You have nothing to query that.
1 Corinthians 15:20-28 says:
“now is Christ risen from the dead, and become the firstfruits of them that slept. For (or gar or seeing) since by man came death, by man came also the resurrection of the dead. For (or gar or seeing) as in Adam all die, even so in Christ shall all be made alive. But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming. Then cometh the end, when ‘he shall have delivered up’ (present active subjunctive) the kingdom to God, even the Father; when ‘he shall have put down’ (aorist active subjunctive) all rule and all authority and power. For (or gar or seeing) he must reign, till he hath put all enemies under his feet. The last enemy that shall be destroyed is death. For (or gar or seeing) ‘he hath put’ (aorist active indicative) 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. And when all things shall be subdued unto him (speaking of the second coming), then shall the Son also himself be subject unto him that put all things under him, that God may be all in all” (1 Corinthians 15:25-28).
Firstly, the usage of the word “for” in this reading simply tells us that what follows is a deduction drawn from what has previously been stated. The repeated usage of the word “for” in this reading demonstrates what is being spoken of is an inference to what has just been stated. In this particular passage, the Greek word
gar links and then further expands upon the fact that the Second Advent is the time “when he (Christ) shall have (finally) put down all rule and all authority and power.” The Greek word ‘gar’, which interprets and carries the same meaning as our English word “for” is used as a key constituent part of the previous statement or subject matter, to simply allocate a fuller enlargement or reinforcement of the matter just mentioned. The word is mainly used for the purpose of argument, explanation or intensification.
Christ, the OT prophets and the NT writers repeatedly enlarge on a truth or recap a matter when relaying truth. This is a common way of teaching. That is all Paul is doing here. After explaining the finality of the second coming he then explains that he will reign until the last enemy is subdued.
Even though it might not seem it at times, God has got his providential hand on our lives. Moment by moment he watches over us. With a Father’s eye He sovereignly brings circumstances and situations into our lives at the right time in order to conform us unto His purposes. When we disobey, He takes the rod of correction to the seat of our understanding.
Second, 1 Corinthians 15:22-24 tells us that “all rule and all authority and power” are finally “put down” or
katargeésee or abolished at the “coming” or parousia of the Lord, which is, as we have established, confirmed in the next sentence as “the end.” The kingdom of God is finally and eternally presented “
up,” whereas the kingdom of darkness is finally and eternally “
put down.” It is this all-consummating last day that ushers in the end (or completion) of all things.
Premils delay the moment when
“all things shall be subdued unto him” by 1,000 years, holding that “the bondage of corruption” with all its awful facets like sin death and decay is only eliminated 1,000 years after the coming of the Lord. They therefore postpone the final
“put down” of all “all rule and all authority and power” till after the Gog / Magog battle in Revelation 20, where they insist Christ finally removes all wickedness from the earth. However, that is not what is being intimated in this passage. This reading actually locates all this at the Lord’s “coming.” It is there that
“all things shall be subdued unto him” (1 Corinthians 15:28),
“when he shall have put down all rule and all authority and power” (1 Corinthians 15:24).
Third, Scripture repeatedly presents a truth and then explains or enlarges upon that truth. After telling us that Christ’s coming sees the termination of the wicked and their evil operations, the writer tells us that Christ’s reign over His enemies must continue until this climactic point. Whilst “all power” is now assuredly given unto Christ “in heaven and in earth” (Matthew 28:18) through His life, death and resurrection, and whilst through this victorious work “he hath put all things under his feet” in a sovereign manner,
we have not yet seen the final subduing of wickedness. This comes at the second coming of the Lord.
Paul is simply reinforcing the thought that he just stated about the climactic coming of Christ. It is the time
“when he shall have put down (or abolished) all rule and all authority and power.” 1 Corinthians 15 verses 24 and 28 repeat the same all-consummating truth.
For Christ to be reigning over His enemies does not in any way suggest these foes are finally and effectively subjugated unto the Lord. No! No more than the rebellious subjects of an earthly monarch who are determined to overthrow the rule of that leader would considered not under the rule of that said king or queen. Whether they like it or not and whether they believe it or not they are subject to the ruler and his laws.
Ephesians 1:20-23 repeats the great truth that Jesus now reigns over His enemies since the cross. We learn that God hath
“raised him from the dead, and set him at his own right hand in the heavenly places, 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: And hath put all things under his feet, and gave him to be the head over all things to the church, Which is his body, the fulness of him that filleth all in all.”
Hebrews 2:6-11 says,
"What is man, that thou art mindful of him? or the son of man, that thou visitest him? Thou madest him a little lower than the angels; thou crownedst him with glory and honour, and didst set him over the works of thy hands: Thou hast put all things in subjection under his feet. For in that he put all in subjection under him, he left nothing that is not put under him. But now we see not yet all things put under him. But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man. For it became him, for whom are all things, and by whom are all things, in bringing many sons unto glory, to make the captain of their salvation perfect through sufferings. For both he that sanctifieth and they who are sanctified are all of one: for which cause he is not ashamed to call them brethren."
