Humble pie?

Mark
Imagine hearing what your brother said about you to a large crowd of people.  You were coming to find where he was and to see why he was surrounded by entire villages.  Someone kindly passed along the message, and your brother eventually heard that you were outside looking for him.  And he said, "Oh, my mother, brother, and sister are right here in front of me" and gestured to the crowd immediately around him.  And if you brother had a real claim to fame, would it be even that much more humiliating to hear that?  There's no way you could say, "Hey, that's MY brother!" (Read, I'm so special because my brother is great!)  Check out Mark 3:31-35, because I'm talking about Jesus.
Do you think Jesus was purposely trying to make his blood family humble by suggesting that they had no special claim to him?  Or perhaps his family already thought he was kind of crazy, as did a lot of others at the time, and so this statement in Mark 3:35 didn't really mean much to them.  But when Jesus spoke, he usually had quite an effect on the crowd, so I'm guessing this statement was meant to get people thinking.
Maybe what he was getting at was that those who actually believed in him and followed him were more precious to him than those who thought they could get by simply on blood relationship, or by doing nothing, essentially.  I think a lesson we could learn here is that Jesus doesn't call us to a life of pride in the fact that we know God.  Rather, we're called to a life where we live out what we believe, every day in all we do, just like the people sitting closest to him in the crowd, because they were focused on following him.
