God wants Noah initially into his Ark at sea (7)
I believe the answer is:
krishna
'god' is the definition.
(Krishna is an example)
'noah initially into his ark at sea' is the wordplay.
'initially' indicates taking the first letters.
'into' means one lot of letters goes inside another.
'at sea' indicates an anagram.
The initial letter of 'noah' is 'n'.
'his'+'ark'='hisark'
'hisark' with letters rearranged gives 'krisha'.
'n' going inside 'krisha' is 'KRISHNA'.
'wants' is the link.
(Other definitions for krishna that I've seen before include "lord?" , "Hare ..., religious sect whose devotees wear saffron robes" , "divine figure" , "Hare ..., religious sect based on Vedic scriptures" , "Most celebrated of Hindu deities" .)
