Is the Millennium a dispensation or just a utopia?

Les teaches that those who come up become the flesh-and-blood people of the Kingdom Age and will have children for a thousand years. There is no death to speak of, no sickness or disease; it will be much like the Garden of Eden, so there will be a tremendous population explosion. The believers who came in the front end are safe for eternity, but their children are born with Adamic natures. As Revelation 20 shows, God first locks up Satan; without Satan on the scene to test those natures, there is no real rebellion or sin, and the Adamic nature remains inoperative. So for a thousand years it is glorious—the utopia everybody is looking for—but it is also a dispensational period of time. Les points out that when Adam and Eve came out of the Garden, everything changed: work by the sweat of the brow, weeds and thistles, sickness and disease, war and famine, and the curse fell. That was a whole different set of circumstances, just as the Millennium is.
