Is there a song with these lyrics...or similar?

"Sometimes we put up walls not to keep people out, but to see who cares enough to knock them down"

Are there any songs that have lyrics like this?
If so thanks..
And/Or is there a place I can look up lyrics-enter in a few words and it finds songs that have those lyrics...

Thanks a ton :)

Go to the music section of yahoo. You can search by artist, song, album or lyrics.

No, I think it's just a life quote.
