What happens to the two witnesses after they preach and the 144,000 go out?
The two witnesses are put to death after they preach to Israel and the 144,000 are sealed and commissioned to carry the gospel of the kingdom worldwide. Their death comes after the preaching that produces the 144,000, and it is tied to the midpoint events described in the teaching.
Les explains that the two witnesses come to the nation of Israel in the Jerusalem area at the beginning. Their preaching leads to the 144,000 young Jewish men being sealed and commissioned to go out and take the gospel of the kingdom around the world. The gospel of the kingdom is the good news that the King is coming, and these 144,000 are saved on the merit of the cross. Then, as Les has already covered, these same two witnesses who came on the scene and whose preaching set the 144,000 in motion are going to be put to death. This occurs in the sequence after the Antichrist, war, famine, and pestilence, as the events move toward the midpoint.
