When will the Jewish remnant believe in Jesus?
The Jewish remnant will believe in Jesus when Christ returns and sets up His Kingdom. After being kept through the tribulation period, they will see Him coming in the clouds of glory and believe in a moment. Israel will be born in a day spiritually, and then the New Covenant becomes reality.
Les explains that this will not be Israel’s own choice; that company of Jews will not suddenly decide to follow God. Instead, when Christ returns and sets up His Kingdom, the remnant of Jews kept through the tribulation period will see Him coming in the clouds of glory. They will believe in a moment, and the nation will be born in a day spiritually, as Isaiah 66 indicates. Then this New Covenant becomes a reality, and God will put His Word and commandments in their hearts. This connects with the remnant Paul deals with in Romans 9, 10, and 11.
