You are badly misinterpreting Revelation 3:10. That verse has absolutely nothing to do with a pre-trib rapture. The word "keep" there is translated from the Greek word "tero" and the word "from" is translated from the Greek word "ek". Here is the only other verse which contains those two words used together.
John 17:15 I pray not that thou shouldest take them out of the world, but that thou shouldest keep (tereo) them from (ek) the evil.
Revelation 3:10 is about the same thing as this verse which means it's about being protected from the hour of trial while still on the earth and not about being taken off of the earth in order to avoid going through trials and tribulations. Jesus even prayed that His people would not be taken out of the world in order to avoid evil and trials, so how can you interpret Revelation 3:10 in such a way that contradicts Jesus's desires for us? Christians have been going through trials and tribulations for almost 2,000 years now, so why would that ever change? It makes no sense.
Acts 14:22 Confirming the souls of the disciples, and exhorting them to continue in the faith, and that we must through much tribulation enter into the kingdom of God.
2 Timothy 3:12 Yea, and all that will live godly in Christ Jesus shall suffer persecution.
You are also badly misinterpreting Revelation 4:1, which has absolutely nothing to do with a pre-trib rapture. John does not represent the church. He alone was caught up to heaven in some way to be shown certain things. That verse is not about the future. It is about what happened to John long ago when he was given visions of things happening in heaven and from the perspective of heaven.
The church is shown as being on the earth and experiencing tribulation after Revelation 4. Such as in Revelation 12:17 when it talks about Christians being persecuted by Satan and in Revelation 13:7 by the beast. There is no basis for the pre-trib rapture theory whatsoever. Jesus certainly didn't teach it.
Matthew 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken: 30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory. 31 And he shall send his angels with a great sound of a trumpet, and they shall gather together his elect from the four winds, from one end of heaven to the other.
Mr. SJ, here is the applicable definition for the English use of "keep from:" to prevent someone or something from doing something
Rev 3:10 is about keeping believers from entering the Trib.
Here's Rev 3:10 (ESV): Because you have kept my word about patient endurance, I will keep you from the hour of trial that is coming on the whole world, to try those who dwell on the earth.
In the above verse, Jesus cites "you" only as believers. He ends the verse by citing a different group: "those who dwell on the earth." He specified about "those who dwell on the earth" that only they will be tried in the hour of trial. Jesus was referring to the 21 judgments of God's wrath that will occur in the hour of trial, otherwise known as the Trib.
In the context of the Trib, "those who dwell on the earth" are always unbelievers. Please see Rev 11:10 for a classic example, in the context of the Trib, of "those who dwell on the earth" as only being unbelievers.
Therefore, what is meant in Rev 3:10 is we believers will be kept from entering the Trib, and only unbelievers will dwell on the earth and be tried by 21 judgments of God's wrath.
So, where do we go if we don't enter the Trib? We are raptured to Heaven. Let me prove that.
1 Th 1:10 is the first verse written about the pre-Trib rapture. Here's 1 Th 1:10 (ESV): and to wait for his Son from heaven, whom he raised from the dead, Jesus who delivers us from the wrath to come.
Definitions of God's wrath are found in Ezekiel 14:21 (NLT): “Now this is what the Sovereign Lord says: How terrible it will be when all four of these dreadful punishments fall upon Jerusalem—
war, famine, wild animals, and disease—destroying all her people and animals.
Rev 6:4 (the 2nd seal) is about wars that will suddenly break out all over the world. Here's Rev 6:4 (NLT): Then another horse appeared, a red one. Its rider was given a mighty sword and the authority to take peace from the earth.
And there was war and slaughter everywhere.
Those wars and their tremendous cost of lives, represent God’s wrath at the beginning of the Trib. That's "the wrath to come" for the purpose of 1 Th 1:10, where “delivers us” relates to the second usage of “deliverance,” in the Bible. That second usage translates to “snatch away.” Therefore, 1 Th 1:10 is about our being “snatched away" just before God’s wrath comes in the Trib, in Rev 6:4.
The furtherance of our being raptured to Heaven, is the sole purpose of Rev 4:1. First, let's be certain that apostle John never left the island of Patmos during his vision of Revelation. In John's own words, it was just one angel who showed John everything he heard and saw in his vision of Revelation. That attestation by John is in Rev 22:8 (NLT): I, John, am the one who heard and saw all these things. And when I heard and saw them, I fell down to worship at the feet of the angel who showed them to me.
Therefore, Rev 4:1 is a future event, being the pre-Trib rapture of the Church, straight to Heaven.
It is 1 Th 1:10 that snatches us away ("delivers us") before the "wrath to come" in the Trib, in conjunction with Rev 4:1, 1 Th 4:16-17 and 1 Cor 15:52.
Those are biblical facts concerning the pre-Trib rapture.
God bless!
