What happens to the people who believe through the ministry of the 144,000 during the Tribulation?
Those who believe through the 144,000 during the Tribulation are converted, but they will be martyred. They are tribulation saints—a great harvest of souls from every tongue, tribe, and nation—gathered under horrible circumstances as gleanings, rather than the main harvest of the church age.
Les explains that the 144,000, as John said in Revelation 7, will see a multitude believe and be converted, but those converts will be martyred. He stresses that the church age remains God's main harvest, while the tribulation saints are the gleanings and the harvesting of the corners. He also says the 144,000 will see a great harvest of souls under horrible circumstances, and Scripture says multitudes from every tongue, tribe, and nation will hear their message. Someone in class suggested the awful circumstances might make belief easier; Les says whether that is the case, he does not know.
