There is a timeline in which to receive Christ, and plumbline that will be drawn, so the time to choose is now. It is man who is separating himself from God not the other way around.
I agree with that but I don’t believe Christians magically get taken from earth 7 years before the destruction. I DO believe we are marked, just like in Ezekiel, God tells him to mark the foreheads of those that sigh and cry over the abominations, and they will be kept safe. I believe the same for us.
Also the children of Israel were protected from the plagues that God sent to the Egyptians and Pharoah; the children of Israel were not removed though.
We will be raptured but the word associated with meeting Jesus in the clouds is a greek word that means ‘as if meeting an official and returning with him’. There is no extended period of time where the earth is without believers.
