Muse a long time on uplifting part of the Bible (5)
I believe the answer is:
erato
'muse' is the definition.
(Erato is an example)
'a long time on uplifting part of the bible' is the wordplay.
'a long time' becomes 'era' (I've seen this before).
'on' says to put letters next to each other.
'uplifting' is a reversal indicator.
'part of the bible' becomes 'ot'.
'ot' back-to-front is 'to'.
'era'+'to'='ERATO'
(Other definitions for erato that I've seen before include "verses she inspired" , "Muse of lyric love-poetry" , "One of nine" , "poetical inspiration" , "goddess" .)
