What resurrection completes the resurrection of all believers of the age?

Les explains that this completes the resurrections of all the believers of the age. The church age believers were already taken out, and the first fruits were taken out before that. Now comes the resurrection of all the Old Testament believers as well as the tribulation believers, and then the Kingdom is ready. Because this resurrection of the Old Testament saints is 75 days into the Kingdom, Les says there has to be a reason. He connects the extra 75 days to Daniel chapter 2, the recovery of Nebuchadnezzar's dream concerning all the great empires of the world, pictured in the image with the head of gold, chest of silver, belly of brass, legs of iron, and feet of iron and clay. These picture the Gentile empires coming down through history. When the Lord returns at the end of the tribulation, He will strike that image on the empire then functioning, the iron and clay, the revived Roman Empire, and crush everything that smacks of Gentile rule and empire.
