Thank you for sharing but I disagree with that presentation in parts.
Yes, Christ had risen to be the firstfruit of those who have slept but scripture has other N.T. saints as firstfruits also.
Romans 8:23And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
So 1 Thessalonians 4:17 is referring to both O.T. saint & N.T. saints being resurrected as the living abiding disciples will go with them meeting the Lord in the air at the pre great tribulation rapture event.
That event is not at His coming as the King of kings because He return with those pre great tribulation raptured saints to touch down on the Mount of Olives to do battle with the world's armies marching against Jerusalem. Zechariah 14:1-5
Then after the world's armies is defeated and Satan is in the pit for a thousand years, that means Christ is on earth when He resurrected those saints that went through the great tribulation as that will happen first before the rest of the dead are resurrected at the Great White Throne Judgment later on. Note verse 5 in Revelation 20:1-6
Those be the firstfruits of the resurrection.
Those who are they at Christ's coming as the King of kings will be vessels of wood & earth in His House as only the power of the second death will not be over them when they are resurrected after the great tribulation to reign with Him for a thousand years.
They will be marrying and ruling as priests & kings during the millennium reign from all over the world in representing Jesus & that City of God, New Jerusalem, on earth. They will be eating from the tree of life in that City of God for the healing of the nations.
So there are vessels of gold and silver, the vessels unto honor that will be like the angels that never die & marry, and then there will be vessels of wood & earth, the vessels unto dishonor for not being ready as they will need to eat from the tree of life & they will marry to raise up the generations following in His one thousand year reign on earth.
