THE 144,000 WITNESSES
Note: Throughout this I shall "paraphrase" scripture for simplicity. I will place a (Pp:) in front each time I do. I will also include the scripture reference for you to look up.
The 144,000 witnesses refers to the Jewish people who will come to realize (after the rapture) during the Tribulation that Jesus was indeed their "Messiah" who was prophesied so long ago. They will then come to a saving knowledge of Jesus. Sorry, Jehovah's Witnesses this means you are wrong.
