Through prayer, God provides abundance (8)
I believe the answer is:
plethora
'abundance' is the definition.
(I've seen this in another clue)
'through prayer god' is the wordplay.
I cannot quite see how this works, but
'prayer' could be 'ora' (I've seen this in another clue) and 'ora' is present in the answer.
This explanation may well be incorrect...
'provides' acts as a link.
Can you help me to learn more?
(Other definitions for plethora that I've seen before include "Excessive quantity" , "(A) glut (of something)" , "almost too much" , "Abundance" , "Abundant supply" .)
