What gospel do the 144,000 preach during the Tribulation?
During the Tribulation, the 144,000 sealed Jewish men proclaim the gospel of the kingdom, not the gospel of grace. They travel globally declaring that the King is coming, echoing the message of Christ's earthly ministry and Peter and the eleven. The age of grace has ended, and the church is gone.
Les explains that after the two witnesses proclaim God's word to Israel, God seals and commissions 144,000 young Jewish men, 12,000 out of each of the 12 tribes, to go around the globe. They do not take the gospel of grace as we know it, but revert to the gospel of the kingdom as it was proclaimed during the time of Christ and Peter and the eleven. Les emphasizes there is a vast difference between the gospel of the kingdom and the gospel of the grace of God. Since the age of grace has ended and the church is gone, these 144,000 tell the world that the King is coming.
