Wearing down love god in embracing love (7)
I believe the answer is:
erosion
'wearing down' is the definition.
'love god in embracing love' is the wordplay.
'love god' becomes 'eros' (I've seen this before).
'embracing' is an insertion indicator.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'in' enclosing 'o' is 'ion'.
'eros'+'ion'='EROSION'
(Other definitions for erosion that I've seen before include "The gradual wearing away by weather" , "Action of wearing away" , "The wearing away by weather 97)" , "dying away" , "A wearing away as of rock by water" .)
