Don't use a choir bank but a female voice bank(the two are quite distinctive and different). The synths also have a bit of filtered white noise on them.

And when applying delay on vocals, (in this case)they're only applied to certain words.

ie. And I find strength in all are fears "all are...all are...all are". The only section that has delay on it is "all are". The point I'm trying to make is that it's not very apparent, yet people will still think it's as easy as wacking delay onto the ENTIRE vocals.
