“Eternity' does not constitute a completely timeless state, but was created along with the spiritual world and coexists with it without end. So that just as time is intrinsic to the world perceived by the senses, so 'eternity' too is intrinsic to the created world of the spirit. Finally, the Day of the Lord, or the eighth day is also described as 'eternal' because it represents the state of the world to come.”
