I believe that when the rapture happens (before the wrath of the 6th and 7th seal, but after the tribulation of seals 1-4), people will doubt that God gathered the church. There will be some lie that they will believe...like aliens or interdimensional beings or something.
I believe that the two witnesses are sent to warn Israel, to testify to Christ, and many, in Israel, will still not believe even though millions of people are gone, graves are open, and the two witnesses are warning/testifying.
Rev 10 is a warning to Israel that the rapture was an act of God, that God loves the gentile Church too. They won't believe until the two witnesses are resurrected and raptured, just as the church was, before the eyes of the world.
Eph 3:1 For this reason I, Paul, the prisoner of Christ Jesus for the sake of you Gentiles–
Eph 3:2 Surely you have heard about the administration of God's grace that was given to me for you,
Eph 3:3 that is,
the mystery made known to me by revelation, as I have already written briefly.
Eph 3:4 In reading this, then, you will be able to understand my insight into the mystery of Christ,
Eph 3:5 which was not made known to men in other generations as it has now been revealed by the Spirit to God's holy apostles and prophets.
Eph 3:6 This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus.
Eph 3:7 I became a servant of this gospel by the gift of God's grace given me through the working of his power.
Eph 3:8 Although I am less than the least of all God's people, this grace was given me: to preach to the Gentiles the unsearchable riches of Christ,
Eph 3:9 and to make plain to everyone the administration of this mystery, which for ages past was kept hidden in God, who created all things.
Eph 3:10 His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms,
Eph 3:11 according to his eternal purpose which he accomplished in Christ Jesus our Lord.
Rev 10:9 So I went to the angel and asked him to give me the little scroll. He said to me, “Take it and eat it. It will turn your stomach sour, but in your mouth it will be as sweet as honey.”
Rev 10:10 I took the little scroll from the angel's hand and ate it.
It tasted as sweet as honey in my mouth, but when I had eaten it, my stomach turned sour.
Rev 10:11 Then I was told, “
You must prophesy again about many peoples, nations, languages and kings.”
Rev 7:9 After this I looked and there before me was a great multitude that no one could count, from every
nation, tribe, people and language, standing before the throne and in front of the Lamb. They were wearing white robes and were holding palm branches in their hands.
This particular word of God is sweet when spoken, but when Israel "digests" it, they will realize what they missed and how wrong they've been.
Rev 3:9I will make those who are of the synagogue of Satan, who claim to be Jews though they are not, but are liars-
I will make them come and fall down at your feet and acknowledge that I have loved you.
Rom 11:11 Again I ask: Did they stumble so as to fall beyond recovery? Not at all! Rather, because of their transgression,
salvation has come to the Gentiles to make Israel envious.
