I may be a few days late, but I downloaded this when I saw the topic and have been listening to it ever since. The verse is great, there's not too much wrong with it. Lyrics and flow were both pretty tight on this. You remind me of Sonny Sandoval of P.O.D. on this. This sounds like something he would do, especially the way the hook sounds. The only thing I don't like is that the hook went on about twice as long as it should have. A second verse (and third?) would have helped, but after reading your comments, I understand why there wasn't one.
In regards to giving you advice on writing more than one verse, I'd have to expand on what chambers said. If you know what you want to say on a track, don't cram it all into one verse. Try expanding on certain ideas and see how it comes together. I think you'll find that a lot more will come to you that's relevant to the subject of the song when you try this. You'll think of things you usually wouldn't, probably since you'll be taking more time to think about the subject/theme of the song. It should help you progress creatively I think too.
Also, I think this song could be expanded. I see that chambers wants to do a verse, but would you let anyone else do a verse too? This could possibly be a great song to get a bunch of artists on and have an extended version or something. Personally, I'd love to drop a verse on this if possible.
Again, great song here.
