It may give me this belief in God (6)
I believe the answer is:
theism
'belief in god' is the definition.
(I've seen this before)
'it may give me this' is the wordplay.
'me this' can be anagrammed to 'THEISM'.
But, I'm unsure how this is indicated.
Can you help me to learn more?
(Other definitions for theism that I've seen before include "Belief in a creator" , "The doctrine or belief in the existence of a God or gods" , "of faith" , "Belief in existence of a God revealed to man" , "Belief in a deity" .)
