First I did not say only 7000 believers will not be deceived. I said 7000 of the elect spoken of by Christ will be filled with the Holy Spirit revealing Satan. Who do you think Paul is talking about in 2 Thess. 2:3 ? He is talking about what he wrote in the book of Romans which God had chosen long before Paul was even born.
You did not make yourself clear enough on your question about the 7000 and where I got it from.
Re-read what I said. It was posted as to where I got both the 7000 elect (not the 144k spoken of in Rev.) but the elect that were chosen to stand against Satan and "reveal" him to the world.
The 7000 bad boy angels are called "men" in the book of Rev.. And again you will disagree until you get a handle on that expression as I said 'Christ was called the son of man, and was also called the son of God.'
When an angel comes to earth, he is called a man. Why, because he looks like men. When we are in heaven we are called "angels" messengers, or as I shared "stars" symbolically in the eyes of God.
I am using symbolics to prove my point, and if you don't have a handle on them, you will never agree. I have been through this a 1000 times and only a few have the desire to seek that truth out of what I have shared.
Do you think Christ is going to kill 7000 "flesh" men in front of the whole world? If He does, what do you think that would do to His authority when God is looking to save as many as He can from Satan and his bad boys.
But if Christ kills 7000 bad angels that are deceiving the world, then you can count on people listening to Christ and coming to Christ. But by then it will be too late for them too.
But, we have the millennium rule of Christ to bring into the fold the "second fruits". That is the main reason of Christ ruling for a thousand years before judgment day.
blessings.
