Will resurrected saints be part of the flesh-and-blood population in the millennial kingdom?

Les explains that during the millennial kingdom, the earth’s citizens will be normal flesh-and-blood people who have children, work, and produce, but without sin, without the adversary, and under Christ’s righteous rule. He says believers will not be part and parcel of that flesh-and-blood population; instead, as resurrected saints they will interface with them. From their place of authority, God will give each believer an area of responsibility, with varying rewards and rule, as illustrated by the account of the talents and ruling over cities. Les admits he cannot explain all the mechanics.
