Tell uplifting story in Bible class (6)
I believe the answer is:
relate
'tell' is the definition.
(as in to tell or relate a story)
'uplifting story in bible class' is the wordplay.
'uplifting' shows that the letters should be reversed in order.
'story' becomes 'tale' (synonyms).
'in' indicates putting letters inside.
'bible class' becomes 're' (Religious Education).
'tale' back-to-front is 'elat'.
'elat' put within 're' is 'RELATE'.
(Other definitions for relate that I've seen before include "Recount" , "Tell (a story)" , "Narrate or connect things" , "feel empathy" , "Tell; connect" .)
