'straight' is the definition.
(thesaurus)

'home in divine surroundings' is the wordplay.
'home' becomes 'nest' (I've seen this before).
'in divine' becomes 'holy' (I've seen this before. I am not sure about the 'in' bit.).
'surroundings' means one lot of letters goes inside another.
'nest' placed inside 'holy' is 'HONESTLY'.
