Why are the 144,000 not preaching the gospel of grace?
The 144,000 are young Jewish men from the twelve tribes who preach the gospel of the kingdom, not grace, because the age of grace has ended, the church is gone, and God has returned to Israel, resuming His program from the early Acts period to proclaim the coming King.
Les teaches that the 144,000 are young Jewish men whose tribal lineage is still intact enough for God to identify 12,000 from each tribe. They are not preaching the gospel of grace because that has ended; the church is gone, and God is right back where He left off with Israel, back up in the early part of Acts. Instead, these young Jewish men will circumvent the globe proclaiming the coming of the King, which is the gospel of the kingdom. All twelve tribes are represented in this group.
