Why will believers who heard the gospel from the 144,000 Jews minister to them at the end of the tribulation?
During the closing days of the tribulation, believers who heard the gospel from the 144,000 Jews will minister to their needs because of their new relationship and because they have survived. Jesus calls the 144,000 His brethren, so serving them is serving Him.
Les explains that during the closing day of the tribulation, believers who have heard the gospel from these 144,000 Jews will minister to their needs because of their new relationship and because they have survived. He connects this to Jesus' words, "inasmuch as you have done it unto the least of these My brethren." Les notes that nobody is a brethren of Jesus except the Jew, so Jesus is referring to the 144,000. In contrast, the goats, the unbelievers, ask when they did not do this, and they are taken off the scene.
