God returning to cross (4)
I believe the answer is:
sore
'cross' is the definition.
(thesaurus)
'god returning' is the wordplay.
I cannot quite see how this works, but
'god' could be 're' (Re is an example) and 're' is found within the answer.
The remaining letters 'so' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'to' is the link.
(Other definitions for sore that I've seen before include "Tender spot" , "Raw or annoyed" , "very much" , "Painful or tender" , "Hurtful to the touch, like rose" .)
