When and how will the remnant of Israel be saved?
The remnant of Israel will be saved at the end of the last three and a half years, when they see Christ returning in glory at the battle of Armageddon. God supernaturally protects them during that period, leading them out of Jerusalem to the mountains southeast, feeding and sheltering them, and then saves every last one.
Les explains that the remnant of the Jews who survive the last three and a half years will, unbeknown to them, make their way out of Jerusalem as one large group, like Israel coming out of Egypt, to the mountains in the southeast. The Antichrist will try to destroy them with an armed force, but God will intervene, just as He opened the Red Sea for Israel; this time He will open the earth and pour the Antichrist's army into it and cover them up. It is a supernatural phenomenon, and Israel's remnant will be safe. God will feed them there for three and a half years, much like the wilderness experience; they won't have to worry about clothes or shelter, because God will take care of them totally. Then at the end of the three and a half years, when they see Christ returning in glory at the battle of Armageddon, and as He pours out His wrath upon Christ-rejecting Gentiles who have gathered in the Middle East, this remnant of Israel will be saved in totality, every last one of them.
