All of this more likely relates to the entire process by which Jesus receives dominion. All of this happened during the life of the disciples. It doesn't mean there won't ever be a time when kingdom building becomes evident on earth. If demonic activity gets to reign supreme on earth for all eternity, then God is not ever bounding them in hell. That's a real problem and why you sir are the heretic not futurists.
Jesus was enthroned when he rose from the dead and ascended into heaven. In his Pentecost sermon Peter declares that, because David knew that God had sworn to him with an oath that he would place one of his descendants on his throne, therefore David looked ahead and prophesied concerning the resurrection of the Christ (Acts 2:30-31).
Indeed, the promises to David were fulfilled in both Jesus’ resurrection and his ascension (Ac 2:30-36).
Therefore, the throne of David has been fully restored in Jesus (Lk 1:32-33; cf. Isa 9:7).
Note that Jesus was installed as King in the heavenly Zion — alongside Yahweh (Ps 2:6; 110:1-2).
His rule is from heaven — over the earth but not on the earth. It’s from heaven that he subdues his enemies (Psalm 110; Mt 26:64).
The author of Hebrews cites from 2 Samuel 7:14 and from Psalms 2, 45 and 110, affirming that all these promises/prophecies have been fulfilled with Jesus having ascended to the Father’s side (Heb 1:3-13).
Likewise, Daniel’s “son of man” vision (Dan 7:13-14) was fulfilled in Jesus’ ascension.
All nations are Jesus’ reward and inheritance (Ps 2:8; Dan 7:14).
He wins the nations through the gospel (Mt 28:18-20; cf. Isa 2:3).
In time, all nations will be converted (Rev 15:4; cf. Ps 86:9).
Consider Paul’s last citation too: Isaiah 11:10 (LXX). Paul evidently viewed this prophecy as being similarly fulfilled in his day via the gospel, as the “knowledge of the LORD” (Isa 11:9) spread throughout the world. Isaiah 11:6-9 depicts perfect harmony between natural enemies (predators and prey) under Messiah’s rule. Indeed, the peace, reconciliation, and security to be enjoyed in the messianic kingdom is a prominent Isaianic theme — see Isaiah 2:4; 9:6-7; 16:4-5; 19:23-25; 32:1-2; 35:9.
And so it is that the gospel brings about peace and reconciliation between former enemies — diverse groups become united under the lordship of Christ. In Paul’s day, the natural hostility between Jews and Gentiles was being eroded as they worshipped God together (Rom 15:5-7; Eph 2:14-15).
Following Paul’s lead, references in the Psalms to the victories and dominion to be enjoyed by David’s royal heirs (e.g., Psalms 2, 45, 72, 110) should be viewed as finding ultimate fulfillment in the incorporation of people into Messiah’s kingdom via the gospel. In this way, peoples and nations are blessed in accordance with the promises made to Abraham — see Romans 4:13; Galatians 3:8, 14 (cf. Gen 12:3; 22:18; Ps 72:17).
But note the spiritual nature of this conquest: Jesus, via the gospel, rules over all who voluntarily submit to him as Lord and Savior. Indeed, Paul’s task as the apostle to the Gentiles was to bring the nations to “the obedience of faith” — the obedience to Christ that true faith inevitably inspires (Rom 1:5; 16:26; cf. Rom 15:18).
John’s last vision (Revelation 21 – 22) shows what Jesus has finally accomplished: Jesus is enthroned in the heavenly Zion, alongside the Father (Rev 22:3b; cf. Ps 2:6; 110:1-2; Ac 2:30-36).
With his enemies destroyed, all things in heaven and on earth have come under his headship (Eph 1:10, 22).
Concerning things in heaven: “Jerusalem” is the final, heavenly reward of the Old Testament saints (Heb 11:10, 16) and the first-century martyrs (Rev 7:14-17; 21:7). We are shown, in Revelation 20:14, the defeat/destruction of Jesus’ last enemy: Death and Hades.
In AD 70 Jesus unlocked Hades-Paradise; the saints and martyrs were released and judged and admitted into the heavenly city — there to live in God’s presence forever (Rev 1:18; 20:11-15; 21:7).
The saints’ admittance into heaven via resurrection represented the end of Man’s long exile — an exile that began with Adam’s expulsion from the Garden and which continued posthumously in Paradise.
Concerning things on earth: Jerusalem is also on earth (Rev 21:2, 10): It represents Jerusalem restored after judgment — in fulfillment of Old Testament prophecy.
• It’s Christ’s Bride — the Church, the people of God (Rev 21:2, 9; cf. Eph 5:25ff.).
• It’s where believers “live” under the New Covenant (Heb 12:22).
• It’s the capital and seat of government of the new (post-70 AD) world order: Jesus, with the Father, is enthroned therein (Rev 22:1, 3b), and the surrounding nations are firmly under his/their rule (Rev 12:5; cf. Ps 2:6-9). The saints co-reign with Christ from Jerusalem (Rev 2:26-27; 5:10; 22:5; Dan 7:18, 27).
• The city (as the Church) serves as a light and ministers gospel healing to the nations (Rev 21:24; 22:2): The wicked outside are invited to repent and enter through the gates (Rev 22:14-15, 17). In time, all nations will come to worship God in Jerusalem (Rev 15:4; cf. Ps 86:9; Isa 2:1-3; Mt 28:18-19).
Revelation therefore shows the throne of David as fully restored, with all nations being blessed through his benevolent rule (Psalm 72; Isa 9:6-7; 11:1-10; 42:1-4; Lk 1:32-33).
Thus, God’s kingdom has come — his eternal kingdom promised in the Old Testament. Of this kingdom Jesus is (and will remain) the king-priest “forever” (Ps 110:1-4; Heb 6:20; 7:17, 21, 24). And since he is king “forever” (2Sam 7:16; Ps 72:5; Isa 9:7; Dan 7:14; Lk 1:33; Rev 11:15), the world itself must continue on, if not literally forever, certainly for a very long time. Sinners (on earth) will always need a priestly mediator to intercede for them (Heb 7:25; Rom 8:34; 1Jn 2:1).
Jesus’ rule and the gospel The gospel is “the good news of the kingdom of God” (Lk 4:43; 8:1; 16:16). It’s the proclamation that, through Jesus, God’s kingdom has finally come (Ac 8:12; 19:8; 20:25; 28:23, 31). Jesus co-rules with the Father (Rev 11:15; Ps 110:1-2; Dan 7:13-14). The gospel calls people to recognize that very fact — to confess him as Lord and as God (Rom 10:9; Php 2:9-11), and to submit to his rule through repentance expressed in baptism (Mt 3:2; 4:17; 28:18-20; Ac 2:36-38).
God’s kingdom is of a spiritual-moral nature rather than political or external. The Pharisees sought an earthly monarchy, like that of David, but Jesus repudiates this notion entirely: 20 … “The kingdom of God does not come with observation. 21 Nor will they say, ‘Here it is!’ or ‘There it is!’ For remember, the kingdom of God is within you.” (Luke 17:20-21, MEV).
To be sure, Jesus is enthroned in heaven and rules over the nations. Yet here, Jesus emphasizes the spiritual-moral nature of his rule. He rules us via his word and Spirit: the kingdom involves godly living and obedience (Rom 14:17; Col 2:6).
We confess him as Lord — as God, and as our king. Thus, the kingdom has its throne in human hearts. As Christians we are incorporated into this kingdom (Col 1:13). Apart from spiritual new birth one can neither perceive nor enter the kingdom (Jn 3:3, 5). Our kingdom “weapons” involve persuasion and reasoned arguments (2Cor 10:4-5; cf. Ps 149:6-9; Jn 18:36).
Jesus’ rule over the nations Jesus’ gospel “conquest” of the Gentiles proves that David’s throne has been restored. James explicitly teaches this in Acts 15:13-21 — his address to the Jerusalem Council: James regards the conversion of the Gentiles as something foretold by the Old Testament prophets (15:14-15), and he goes on to cite just one example: Amos 9:11-12. Jesus has raised up David’s fallen tent; he’s rebuilt its ruins and restored it to its former glory (15:16). All this so that the Gentiles might seek the Lord, for they, too, belong to him (15:17). )
And so, through the gospel, Christ exercises dominion over the nations. But note that this is a spiritual, not a politico-military, conquest: Jesus conquers through the gospel; he rules over all who voluntarily submit to him as Lord and Savior.
Psalm 2 notes that while the nations are Jesus’ reward and inheritance, their rulers don’t submit to him willingly. Of necessity he rules “with a rod of iron” (2:9). So he rules them providentially, punishing and disciplining them as he deems necessary.
