Image of god doing nothing, by the sound of it? (4)
I believe the answer is:
idol
'image of god' is the definition.
(I've seen this before)
'doing nothing by the sound of it?' is the wordplay.
'doing nothing' becomes 'idle' (I've seen this in another clue).
'by the sound of it?' shows a homophone (sound like).
'idle' sounds like 'IDOL'.
(Other definitions for idol that I've seen before include "Object of worship (or love?)" , "Something worshipped" , "Superstar; graven image" , "Graven image or greatly admired person" , "Worshipped image; lido (anag.)" .)
