Is there a remnant of Jewish believers today?
Yes, a remnant of Jewish believers exists today. In this age of grace, though predominantly Gentile, a small percentage of Jews have believed the gospel of grace, chosen according to grace, not law or Judaism. Their testimonies confirm Paul's teaching that God preserves a remnant, as in Elijah's day.
Les teaches that God has always kept a remnant, a doctrine traceable from Genesis through Revelation. In this age of grace, which is predominantly Gentile with some Jewish exceptions, Paul says there is a remnant—a small percentage of Jews who have become believers of the gospel of grace, elected according to grace, not law or Judaism. Les recently read a book of testimonies of Jews from all backgrounds who became believers of this grace gospel, and he found it amazing how God manipulated their lives until they believed Jesus of Nazareth was the Messiah who died for their sins. They are a remnant, very few, but they are there, confirming Paul's words, just as Elijah was shown 7,000 who had not fallen to idolatry. So today a remnant of Jews recognizes the gospel of grace and the election of grace.
Even so then at this present time also there is a remnant according to the election of grace.
