The Problem of Hard Heartedness (Mark 6:45-56)

We are probably tempted to have our favorite villains in the Gospel stories.  We have the Pharisees and the Scribes who conspired to send Christ to the cross.  We have Judas who betrayed Christ and should have known better.  We have Pilate who compromised justice to save himself from having a potentially huge political mess.  However, we do not think about our issues and the gospel?  What about the disciples and their struggle?
