We can see him with the ' mind's eye ' by what is happening around us - Please remember John14:19 that the world would behold him No more.
I find Revelation is written in very-vivid word pictures for us (Rev. 1:1) so every eye seeing Jesus does Not have to be literal.
People can observe around-the-world evidences around them such as what Jesus said at Matthew 24:14; Luke 21:11 and the list at 2 Timothy 3:1-5,13.
Matt 24:30 “Then will appear the sign of the Son of Man in heaven. And then all the peoples of the earth will mourn when they see the Son of Man coming on the clouds of heaven, with power and great glory.
Matthew is not Revelation.
The scriptures you gave are about the signs of Jesus coming. You believe Jesus has returned already, so why do you give those scriptures?
I also noticed in one of the scriptures that it says "this gospel of the kingdom shall be preached", it does not say another gospel shall be preached. The JW gospel is another gospel that was not preached in the first century and Jesus mentioned nothing about it. For Jesus all needed to be born again and were promised the Holy Spirit to become God's children and all were to be in the Covenant and in the Body of Christ etc.
Matt 24:14 And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come.
New Jerusalem is heavenly Jerusalem. Jerusalem above being the seat of government - Galatians 4:26
How could the measurements of heavenly Jerusalem fit on Earth ___________
As the scriptures tell us, the heavenly Jerusalem is going to come down to earth and God will dwell there. It is no doubt the right size for the ones who will dwell there. That is where God said He wanted to dwell forever. God will fill this city, because God is everywhere and neither the heavens nor the heaven of the heavens can contain God. (1Kings 8:27
Rev 3:12 The one who is victorious I will make a pillar in the temple of my God. Never again will they leave it. I will write on them the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on them my new name.
Rev 21:1 Then I saw “a new heaven and a new earth,” for the first heaven and the first earth had passed away, and there was no longer any sea. 2 I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband. 3 And I heard a loud voice from the throne saying, “Look! God’s dwelling place is now among the people, and he will dwell with them. They will be his people, and God himself will be with them and be their God.
Please notice the dead people mentioned at Hebrews chapter 11 because they are all still dead people - Hebrews 11:13; Hebrews 11:39-40.
This is why the 'future tense' is used in connection to the 'future resurrection' at Acts of the Apostles 24:15
www.jw.org
The future tense is used at Acts 24:15 because the resurrection was and still is in the future,,,,,,,,,both resurrections. The Old Testament saints are not amongst the "wicked" mentioned in Acts 24:15. If you want to put yourself amongst the wicked in the 2nd resurrection, that is up to you. The blood of Jesus has cleansed us and made us righteous however. Even the great crowd (Rev 7:14) have had their robes
cleansed by the blood of the Lamb.
Yes the OT saints of Heb 11 have not been resurrected yet and nobody has.
They do end up in the New Jerusalem however which comes down out of heaven and in the Kingdom of God.
Heb 11:13 All these people were still living by faith when they died. They did not receive the things promised; they only saw them and welcomed them from a distance, admitting that they were foreigners and strangers on earth. 14 People who say such things show that they are looking for a country of their own. 15 If they had been thinking of the country they had left, they would have had opportunity to return. 16 Instead, they were longing for a better country—a heavenly one. Therefore God is not ashamed to be called their God, for he has prepared a city for them.
Matt 8:11
I say to you that many will come from the east and the west to share the banquet with Abraham, Isaac, and Jacob in the kingdom of heaven. 12But the sons of the kingdom will be thrown into the outer darkness, where there will be weeping and gnashing of teeth.”…
Luke 13:28 There shall be the weeping and the gnashing of teeth, when ye shall see Abraham and Isaac and Jacob and all the prophets in the kingdom of God, but yourselves cast out.
