Because that is what you want it to say. .....different than the facts.
Validated...I might say.......by scripture which tells us we will be ...."kept from the hour (major destruction) that shall come upon all the earth".....
And it also says, Rev 2:10 Fear none of those things which thou shalt suffer: behold, the devil shall cast some of you into prison, that ye may be tried; and ye shall have tribulation ten days: be thou faithful unto death, and I will give thee a crown of life.
So, quoting from one letter is meaningless since the opposite is promised in another letter. Neither is even addressing the rapture anyways. Why go to a passage that actually is speaking of rapture? I know why, because it won't say it's a rapture before trib happens. That's why pretribs always avoid actual rapture passages.
