God in bar (4)
I believe the answer is:
mars
I believe this clue is a double definition.
'god' is the first definition.
(Mars is an example)
'bar' is the second definition.
(chocolate bar)
'in' is the link.
(Other definitions for mars that I've seen before include "part of suite" , "Damages - planet" , "one associated with war" , "blights" , "Spoils - heavenly body" .)
