Is the current age of grace predominantly Gentile?
The current age of grace is predominantly Gentile. Paul describes it as Gentile only with some Jewish exceptions, meaning the vast majority are Gentiles, while a small remnant of Jews also believe the gospel of grace according to election, not of law.
Les teaches that God has always kept a remnant, from Genesis through Revelation. In this age of grace, Paul says it is predominantly Gentile, Gentile only with some Jewish exceptions. There remains a small percentage of Jews who have become believers of the gospel of grace, a remnant according to the election of grace, not of law or Judaism. Les also shares a book of testimonies of Jews who came to believe Jesus of Nazareth is the Messiah, noting that though very few can believe, they are there, just as Elijah was shown 7,000 who had not fallen to idolatry.
