Strange sacrifices back at home for god (4)

I believe the answer is:

odin

I'm a little stuck... Click here to teach me more about this clue!

'for god' is the definition.
(Norse god)

'strange sacrifices back at home' is the wordplay.
'strange sacrifices back' becomes 'od' (I can't justify this - if you can you should give a lot more credence to this answer).
'at home' becomes 'in' ('I'm in' can mean 'I'm at home').
'od'+'in'='ODIN'

Can you help me to learn more?

(Other definitions for odin that I've seen before include "King of Norse gods" , "Mythological Norse god of war" , "Supreme god of Scandanavian myth" , "Pagan god" , "Legendary ruler" .)

I've seen this clue in The Independent.
