Some will come through the tribulations and be saved. Remember who was with Daniel in the lions den? His three students in the furnace? He is a very loving GOD. But our understanding capacity right now as to His ways and reasons are limited to what our minds can grasp. Many things in this world are not to be understood until GOD allows it to be. That includes our physical death and eternal life afterward.
I also agree we don’t know the facts and its because God has not prepared us to.
With that said, I believe the early rapture is pie in the sky and that we, as Christians, are scared of what’s coming (rightfully so) and its easy to believe we’ll be whisked away before the bad stuff happens.
It just isn’t so, IMVHO.
