So, will the overcomers literally be sitting with Jesus in His throne?! That must be one big throne! Or can you see the same logic applies here, that "sitting on the same throne" is metaphor for sharing authority?
Yes, it might mean that they will be sharing the Lord's reign and He will reign on the earth:
"When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory" (Mt.25:31).
Would you please give me your interpretation of the meaning of the words of the Lord Jesus there?
I really would like to know your concise definition of "David's throne". Do you think it is a position of rule over Israel? Or a position of rule over the whole earth?
At the least it refers to an earthly position of rule over Israel but it will eventually be world wide.
So, you don't think Daniel 7 is describing what happened at the ascension? The son of man was coming with the clouds - UP TO HEAVEN - for he approached the Ancient of Days in his presence. Fits perfectly with the description of Ephesians 2 where Jesus sat down at the right hand and was given all authority.
No I don't. There are several instances in the Scriptures that speak of the Lord coming in the clouds when He returns to earth but I am not aware of any verses in the entire Bible which uses similiar language to describe Him GOING TO heaven.
Perhaps you are aware of some?
When will it ever happen that ALL peoples and nations will serve Him? There will always be some that reject His authority, until the final judgement where the wicked are judged.
The Lord Jesus' words at Matthew 24 were in answer to this question:
"Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the age?" (Mt. 24:3).
Earlier the Lord Jesus spoke the parable of the "tares of the field" where He described what would occur at the "end of the age":
"He that soweth the good seed is the Son of man; The field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; The enemy that sowed them is the devil; the harvest is the end of the age; and the reapers are the angels. As therefore the tares are gathered and burned in the fire; so shall it be in the end of this age. 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; And shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of their Father. Who hath ears to hear, let him hear" (Mt. 13:37-43).
Here we can see that the Lord Jesus speaks of a harvest that will happen at the "end of the age", the "end of this age." He also makes it clear that the harvest will take place in the field, and He says that the "field is the world."
Obviously a world wide harvest did not happen in the first century. Before the kingdom will be set up on the earth it will be necessary to take out all of those who are not born again (Jn.3:3). After that happens then the kingdom will be set up and then ALL peoples and nations will serve Him.
Let's assume that you are correct and Christ's Kingdom is not a reality until ALL people are serving him.
1.) Jesus doesn't have a Kingdom in Matthew 25:31 when he sits on the throne, because he doesn't separate the sheep from the goats until AFTER he sits down. IE: there are rebellious people still around after he sits down.
That will happen at the end of the age (which precedes the kingdom age) and the following prophecy will be fulfilled then:
"The Lord at thy right hand shall strike through kings in the day of his wrath. He shall judge among the heathen, he shall fill the places with the dead bodies; he shall wound the heads over many countries" (Ps.110:5-6).
With the reference to "kings" it is certain that a world wide judgment is in view. Again, that prophecy has not yet been fulfilled.
2.) Jesus doesn't have a Kingdom when Satan leads a final rebellion at the end of millenial reign.
Sure He will. There will be people in the kingdom in flesh and blood bodies and at the end of the 1000 years Satan will deceive some of them and they will attack the saints. But then these rebels will be destroyed.
If you believe the Kingdom of God is still future, what Kingdom was "at hand" when Jesus was on earth?
Due to Israel's unbelief the kingdom has been delayed until the Lord's return to the earth:
"And then shall they see the Son of man coming in a cloud with power and great glory. And when these things begin to come to pass, then look up, and lift up your heads; for your redemption draweth nigh. And he spake to them a parable; Behold the fig tree, and all the trees; When they now shoot forth, ye see and know of your own selves that summer is now nigh at hand. So likewise ye, when ye see these things come to pass, know ye that the kingdom of God is nigh at hand" (Lk.21:27-31).
According to your ideas the Lord did come in 70AD but what happened then had nothing to do with the kingdom being nigh at hand. According to Peter when the Lord Jesus returns to the earth the Jews will enjoy a refreshment from the presence of the Lord Jesus (Acts 3:19-20).
That did not happen in the first century or anytime since.
