God inspired by prayer a lot (8)
I believe the answer is:
plethora
'a lot' is the definition.
'god inspired by prayer' is the wordplay.
'god' becomes 'thor' (Thor is an example**).
'inspired by' is an insertion indicator.
'prayer' becomes 'plea' (plea is a kind of prayer).
'thor' placed inside 'plea' is 'PLETHORA'.
(Other definitions for plethora that I've seen before include "Abundant supply" , "Cornucopia -- superfluity" , "Excessive quantity" , "Glut, over-abundance" , "surplus" .)
