You have mentioned that after the rapture, the Holy Spirit will be taken out of the way (2 Thes. 2:7). Does that mean all of heaven’s good angels will be taken away as well? Planet earth will be a horrific place if the spiritual realm is 100% evil.
There’s no mention in the Bible of angels being removed from Earth during the end times. It will be a time of unparalleled warfare in the spiritual realm and much of it will take place on Earth.
It’s important to note that although the Holy Spirit will be taken “out of the way” when the Church is raptured, that doesn’t mean His presence will not be felt in the world. It means He will no longer serve as the restrainer of evil and the guarantor of the Church’s inheritance. As soon as we arrive in Heaven we will receive our inheritance and will no longer need a guarantor.
While the Holy Spirit won’t be sealed in the hearts of post rapture believers like He is with us, He will still be with believers as He was in Old Testament times, commensurate with their faithfulness and perseverance (Rev. 14:12, Rev. 16:15).
And remember, it’s the Holy Spirit who convicts people of their sins and and softens their heart to receive the faith to believe.
But you’re correct in saying that the world will be a horrific place during that last seven years.
