Thank you. That's a great point! And now with that in mind, read this following verse and see how they fit together.
Matthew 28:18
Then Jesus came to them and said, “All authority in heaven and on earth has been given to me. 19 Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.
In this passage Jesus tells us that he was given all authority on earth (as well as heaven). Not only that but he immediately began exercising his authority through the disciples telling them to spread the gospel, baptize people and advance the kingdom of God by teaching them the word of God. He concludes by saying "I am with you always".
The above verses that you refer are about the SPIRITUAL KINGDOM.....----Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,----
You have forget to include the last sentence ...---to the very end of the age.---
And surely I am with you always,
to the very end of the age.
You see? He (the word of God) is already ruling over the earth (as well as heaven). It helps if you stop thinking of Jesus as a man, and start thinking of him as the word of God.
The part "he shall rule them with a rod of iron" sounds like a scary warning to all the unbelievers, but in actual fact, the word translated as "he shall rule them" is the Greek word "poimanei" which means to shepherd, specifically God's flock. He shepherds with a staff of authority, made of iron. Which means he has ultimate authority that can not be broken.
It follows the description of the two edged sword coming out of his mouth. This is obviously symbolic for the two edges of His word. The one edge which comforts those who accept Him (shepherds God's people), and the other edge which smites those who reject Him (smite the nations). The word of God has had this authority since He was resurrected from the dead, and He will still have this same authority when He returns, as we see in Revelation 19.
You're right that God said "I will make the nations your inheritance, the ends of the earth your possession." in Psalms chapter 2, and God kept that promise. That promise was fulfilled at the resurrection.
... Stop expecting a man-king, as the Jews did. The word of God is our king and He rules today. And the doubled edged sword that it is, will either save you or condemn you.
I am not expecting a man King....the Jews and nearly all the whole world will fall for a -man king- during the Trib.
The King i am expecting... which we know will -physically- come in power and glory to defeat His enemies after the Tribulation is described in Revelation 19
Revelation 19:11-21
11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness
he doth judge and make war.
12
His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean
....
19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army.
20 And the beast was taken, and with him the false prophet that wrought miracles before him, with which he deceived them that had received the mark of the beast, and them that worshipped his image. These both were cast alive into a lake of fire burning with brimstone.
21
And the remnant were slain with the sword of him that sat upon the horse, which sword proceeded out of his mouth: and all the fowls were filled with their flesh.
The word of God does not need to appear in physical form in order to rule. If that were the case, then how could he rule both heaven and earth? Would he have to go back and forth a lot?
While Jesus will reign on the Earth God the Father is in Heaven keeping an eye on the Heaven's business....Below is the mission that Jesus will have to do when He will return on Earth ----//For he must reign, till he hath put all enemies under his feet.----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.---The last enemy that shall be destroyed is death....
1 Corinthians 15
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.
