To me this song is written from God's perspective to us, as a whole. It's basically saying that there is a reason that he chose us to save, and not to forget that. When it seems that life has no purpose, and you're just waiting for someone to tell you what to do, remember this, and know that God is in charge of your life.
Sorry if you're not religious, but Anberlin is christian, and that is only one interpretation. Don't freak out on me. Peace.
