First of all, the above passage doesn't clearly state that the Holy Spirit will be taken out of the earth. It doesn't even clearly state that the restrainer is the Holy Spirit. The restrainer could possibly be some angelic being assigned by God. However, the bottom line is that Scripture is not clear about the identity of the restrainer, and hence we shouldn't automatically assume his identity. It only states that, the "restrainer" (whoever he is) will be taken out of the way. It doesn't say that the "restrainer" will be taken out of the earth, altogether.
If I said that a disabled car which is blocking the roadway has to be "taken out of the way" by a tow truck to haul it away in order to re-establish access on the roadway for others, I'm not implying that the disabled car is removed from the earth altogether.
In the same way, the restrainer would move out of the way of the Antichrist, so that the Antichrist can come into power. It doesn't mean that the restrainer has to leave the earth altogether for that to occur.
Furthermore, another passage in Revelation reveals something in regards to whether the Holy Spirit is on earth during the Tribulation. Isn't Revelation 11:11 referring to the Holy Spirit? If the Holy Spirit has left the earth altogether before the Tribulation starts,
(1). how can the two witnesses testify on the earth and perform signs and wonders (refer to Rev. 11:5-6) without the Spirit empowering and working through them?
(2). how can He resurrect the two witnesses from death if He left the earth before the Tribulation?
(3). how can God be omnipresent (one of the attributes of God) if His Spirit leaves the earth altogether before the Tribulation?
Revelation 11:11 (authorized KJV):
"And after three days and an half the Spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them."
Pre-trib teachers also misinterpret Matthew 16:18 and teach that Satan and his demons are not able to conquer the Church, and therefore, the Church will not go through the Tribulation. The above passage doesn't mean that at all.
Matthew 16:18 talks about the gates of Hades (the power of Death). This is not referring to Satan nor his demons. Christ was saying that Death (spiritual death- separation from God in eternity) would not be able to conquer the Church. This of course is the message behind the Gospel and salvation. However, physical death is still a reality and is something all humans, including the Church, have to face. However, even physical death is only temporary. Both the saints and unbelievers who have died will be resurrected in the future to enter eternity. The saints will be resurrected at the First Resurrection and will have eternal life. However, the unbelievers/the wicked, will be resurrected later at the second resurrection (after the millennial reign of Jesus Christ) and face eternal torment in the lake of fire and burning sulfur. This is known as the "second death", and it is an eternal state (this group will have to die twice because of sin and will never be able to have eternal life). Thus, both God and I are pleading with everyone who is reading this:
(1). repent of your sins and turn away from them (stop sinning),
(2). turn to God instead by putting your faith in His Son- Jesus Christ. Call upon His name.
Don't choose to continue to indulge in sin which will result in two deaths for you. Choose eternal life instead by pursuing righteousness. Why choose to be destroyed and tormented because of your love for sin/evil?
According to the pre-trib view, the first resurrection and the Rapture occur before the Great Tribulation. This clearly contradicts the Bible. In Revelation 20:4-6, it teaches that the first resurrection will include the saints who died during the Great Tribulation. Thus, the Rapture can only occur after the Great Tribulation.
Furthermore, Revelation chapters 12 and 13 clearly teach that Satan and the Antichrist will have the power to persecute Israel (the woman) and also all the followers of Christ (the saints- which would logically mean the Church) during the Tribulation. The KJV interestingly says the "remnant of her seed" in Revelation 12:17. First of all, who is the seed of the woman? I think the answer is given in Genesis 3:15. I believe that the seed is referring to Jesus Christ in both passages. So then, who are the remnant of this seed (Jesus Christ)? I believe they are all the followers of Jesus Christ (the Church/the saints)- those who have the testimony of Jesus Christ (I believe this testimony of Jesus Christ is perhaps His spiritual DNA in believers). I believe that the "remnant" is the last generation of the Church which will be alive at the time of the Tribulation. There have been many generations of the Church from the time of its early inception, which was around 2,000 years ago. All generations constitute the Church, however, only the last generation will go through the Great Tribulation. I believe this is what the remnant is being referred to in this passage.
1 John 3:9 (authorized KJV):
"Whosoever is born of God doth not commit sin; for his seed remaineth in him: and he cannot sin, because he is born of God."
Refer also to Luke 8:11, John 15:4-8, Psalm 45:16, Rev. 20:4, Matt. 8:11-12, and Luke 13:28-29).
Revelation 13:7 (authorized KJV):
"And it was given unto him to make war with the saints, and to overcome them: and power was given him over all kindreds, and tongues, and nations."
