Leviticus - Different

I'm still slogging through Leviticus. It's probably one of the most difficult books to get through trying to deal with some awful strange stuff - how to properly dissect a bird? Where to toss the blood? It seems, though, that a lot of Leviticus is concerned with God's people being distinctively different from everyone else around. The words "Holy" and "special" are used a lot. It might be useful to think about how it is that we are different. Do we really stand out as God's people? As the song goes, do people really know us by our love? Maybe we blend in a bit too well with the world around us. Should I let my beard grow long?
