What is Zoë life?

Zoës were resurrected first and most have already been resurrected. Those who are resurrected as Zoës have the same kind of bodily form Jesus had after his resurrection. Zoë’s share the life of God: They are immortal. They cannot be harmed or killed. They have bodies and see, hear, and feel exactly as they did in their first lives. They do not get hungry but they can eat food, but only do so when eating serves a second function (sharing food is a way of sharing love). Zoës can change their appearance at will and can materialize where needed: Their physical bodies act as an extension of their thought. See the Gospel accounts of Jesus after his resurrection for more details.
Origins of the terms:

“The Biological sort [of life] which comes to us through Nature, and which (like everything else in Nature) is always tending to rundown and decay so that it can only be kept up by incessant subsidies from Nature in the form of air, water, food, etc., is Bios. The Spiritual life which is in God from all eternity, and which made the whole natural universe, is Zoe. Bios has, to be sure, a certain shadowy or symbolic resemblance to Zoe: but only the sort of resemblance there is between a photo and a place, or a statue and a man. A man who changed from having Bios to having Zoe would have gone through as big a change as a statue which changed from being a carved stone to being a real man.” — C.S. Lewis.
