How are the 144,000 sealed and sent out?
At the onset of the seven years, the two witnesses minister in Jerusalem. Out of their ministry, the 144,000 are sealed and designated, then sent out into the world to proclaim the Gospel of the Kingdom, announcing that the King is coming to set up His Kingdom.
Les explains that at the very onset of the seven-year period, as soon as Israel signs the treaty, God sends the two witnesses to Jerusalem. They proclaim salvation to the nation of Israel. It is out of their ministry that the 144,000 are sealed and designated, and then sent out into the world to proclaim the Gospel of the Kingdom—the message that the King is coming and will set up His Kingdom. Revelation 11:3 specifies the two witnesses prophesy 1,260 days, which is three and a half years. At the end, they are killed, their bodies lie in the streets of Jerusalem, and they hear a great voice from heaven saying, 'Come up hither.'
