Hello mwc 68, thank you for your comment.
Actually, I was answering the original extinction thar was "When does the rapture occur?"
Our friend was correct in that it is once, but that was not the question.
As it happens, it has already occurred, when the Michael Prince of the Sanctuary stood up (Daniel 12:1) at the end of the Appointed Times of the Nations in 1914 C.E. when there was war in heaven and World War on the earth, brining tribulation to the nations.
It was then that the "Little Flock" whom Jesus had chosen, were raised up as a new creation of immortal spirit creatures (1 Corinthians 49-54; 2 Corinthians 5
to join him in the air and cast Satan out of heaven. (Revelation 12:7-12)
