[ratty]

looks spot on to me.
the kanji is appropriate.
the phrase itself is a little obscure *descend from above* could be written differently depending on what is descending
and whether its a command
or if it is saying the "gift from god" person is doing the descending.

context could change it a little but with religious phrases like that they are actually kinda open to interpretation so if you have interpreted it how your friend feels it means then you've got no problems.
