I don't know him personally so I can only speak to the song. And I think he's assuming quite a bit with lyrics like that.
He's only stating "if I had those things" it wouldn't be enough. I being a part of a church, see where he's coming from, with such a great heritage of songs, one of my favorite lines is to a song is "Riches I heed not, nor men's empty praise" from Be Thou My Vision. It again is saying "if I had these things" it would pale in comparison to Christ.
However that being said, I do totally get that people outside of that heritage, it maybe doesn't make that much sense. Though I never got how most thrice fans got songs like Beggars or all the world is mad for the same reasons.
