Nuns, accepting Jesus at last, resist going awry (7)
I believe the answer is:
sisters
'nuns' is the definition.
(nuns often use the title 'sister')
'accepting jesus at last resist going awry' is the wordplay.
'accepting' indicates putting letters inside (inserted letters are accepted).
'at last' indicates one should take the final letters.
'going awry' indicates an anagram.
The final letter of 'jesus' is 's'.
'resist' with letters rearranged gives 'siters'.
's' inserted inside 'siters' is 'SISTERS'.
(Other definitions for sisters that I've seen before include "Nuns - nurses - siblings" , "Nuns' titles" , "Family relatives" , "Aunts may be" , "Relatives in hospital?" .)
