So regardless of which sex he is referencing in the song, I think it is about being with someone for quite some time and in the beginning you memorize their face, where beauty marks are, etc. And this song is a realization that after some time, he is still very much in love with this person but cannot express it as it is useless even trying. So he writes this song instead to express. And as for the brother part, maybe it is because he has been with the individual for a lengthy amount of time so it feels like they've grown up together in many ways. Like they have always been there. Like a sibling. I don't think this song is about Jesus and it shouldn't matter about which gender it is about though the obvious use of brother gives it a male connotation.
