Bother to reject immorality for God (6)
I believe the answer is:
adonis
'god' is the definition.
(Adonis is an example)
'bother to reject immorality' is the wordplay.
'bother' becomes 'ado' (I've seen this before).
'to reject' says the letters should be written backwards.
'immorality' becomes 'sin' (sin is a kind of immorality).
'sin' in reverse letter order is 'nis'.
'ado'+'nis'='ADONIS'
'for' is the link.
(Other definitions for adonis that I've seen before include "Fit bloke" , "Archetype of male beauty" , "Most 8 Greek youth" , "lovely man" , "one deemed to be beautiful" .)
