With respect, it hasn't just yet.
John 10:16
I have other sheep that are not of this fold. I must bring them in as well, and they will listen to My voice. Then there will be one flock and one shepherd.
^ This is what's been happening for 2000 years in fulfillment of Matthew 28:19-20. The Messiah has been gathering His sheep from other (gentile) folds into one flock to reestablish His kingdom on earth ("thy kingdom come, thy will be done, on earth..."). Those of the gentiles who hear His voice are these sheep. Romans 11 explains this; this is time for the fullness of the gentiles to come into the fold.
Once the full number comes in the rest of the plan for "full" Israel (Jew & Gentile) continues with the resurrection/transformation & gathering. The apostles didn't understand this at first...
Acts 1:6-8
When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel? 7 Jesus replied, “It is not for you to know times or seasons that the Father has fixed by His own authority. 8 But you will receive power when the Holy Spirit comes upon you, and you will be My witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth
The Almighty took the Levites as His portion from among the tribes of Israel to be His priests TO those tribes. So likewise, the Messiah gathers His portion from among the nations of the world to be His priests TO those nations. The gathering of the priests comes first. They will not truly minister to the nations until the following occurs within all of Israel (Jew & Gentile)...
Jeremiah 31:33-34
33 “But this is the covenant I will make with the house of Israel after those days, declares the LORD. I will put My law in their minds and inscribe it on their hearts. And I will be their God, and they will be My people.
34 No longer will each man teach his neighbor or his brother, saying, ‘Know the LORD,’ because they will all know Me, from the least of them to the greatest, declares the LORD. For I will forgive their iniquities and will remember their sins no more.”
^Proof: There will no longer be necessary schools of bible teachers or a multitude of denominations or interpretations to contend with, and deception will be prevented (because satan will be bound). All of Israel will know the Almighty, through and through, perfectly, in order to teach others. This event hasn't happened yet because Israel hasn't be reassembled, as is prophesied here...
Ezekiel 37:13-14
13 And ye shall know that I am the Lord, when I have opened your graves, O my people, and brought you up out of your graves, And shall put my spirit in you, and ye shall live, and I shall place you in your own land: then shall ye know that I the Lord have spoken it, and performed it, saith the Lord.
^The 1st resurrection/transformation event must happen first, followed by the regathering of true, complete, Israel (Jew & Gentile) back to the land...
Ezekiel 37:21
21 And say unto them, Thus saith the Lord God; Behold, I will take the children of Israel from among the heathen, whither they be gone, and will gather them on every side, and bring them into their own land:
^This passage is completely true...but it was said prior to satan falling. As Revelation 12 explains, when the Son ascended to the throne in heaven (which already happened in Acts 1; 1st century), war broke out, and then satan fell having great wrath knowing his time is short.
And now today, with over 2000 differing denominations claiming to have a pure truth, chasing 2000 years of deadly persecution by the Catholic church (as so-called representatives of God), sprinkled with a profuse amount of mistranslation - all of this confusion the result of satan - how can a person be sure the gospel of Christ is the truth these days? satan deceives the whole world.
This is why he must be imprisoned first so that pure truth can be preached without leaven. Those who DO hear the truth now do so because they specifically are CALLED to be priests. Until all priests are called and transformed/resurrected, the world is left to its own devices by God Himself. This is still step 1.
Romans 2:18-21 [brackets mine]
18 For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us. [i.e. the transformation]
19 For the earnest expectation of the creature [i.e. the creation; the earth] waiteth for the manifestation of the sons of God.
20 For the creature [i.e. the creation; the earth] was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
21 Because the creature [i.e. the creation; the earth] itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
^When they manifest (upon transformation into Glory), the children of the living God will deliver the world from its bondage to corruption. His first step is to manifest them, which - again - is the transformation/resurrection event. Notice Paul is preaching this so he more than anyone would know. Each achieves life in their own order: Christ, the firstfruits, then those at His coming, then the end when the world is delivered...1 Corinthians 15:23. The Millennium Reign.
Brother, there is an order to all of it. I have no problem with the passages you've referenced, but there is an order. For instance, verse 4 to verse 14 is the Messiah's entire answer to the disciples' question in summary form.
"Tell us, when shall these things be? and what shall be the sign of thy coming, and of the end of the world?"
1) Deception (horseman 1)
2) Rumor of wars (horseman 2)
3) Famines (horseman 3)
4) Diseases (horseman 4)
5) Earthquakes & Martyrdom of followers (5th seal)
6) Love grows cold
7) False prophets
9) And then this gospel shall be preached
10) And then the end comes when you, therefore, see the abomination of desolation
Notice that the preaching of the gospel comes at least after the first 5 seals are broken. I'm not disagreeing that this is happening now (in fact, I believe many of the seals have been broken already), I'm just noting the order of events to show that understanding the order in the Almighty's overall plan is important.
Blessings.
