We must not confound palingenesia and anagennao; palingenesia is a change of state as Matt. 19, and used for a recovery of wealth when fortune has been lost. Anagennao is being born "again," so anablepo, anakainizo, etc., it has the sense of "up" often, but "again" or "back"—the beginning of something new, with the sense of the contrary of what it was before, so analuo, anakampto, anakalupto, etc. The other sense is pretty much our use of "up"; see 1 Peter 1:3-23; Titus 3:5.
