Jesus confronted religion. He confronted the selfish religion of the scribes and Pharisees of His day. They had cold hearts. They were seemingly unconcerned for the lost. They were self-righteous. They placed themselves in place of God. We need to be careful to avoid temptations to fall in the similar traps today.
The idea of zombies is a current fad in entertainment. But did Jesus ever encounter the walking dead? Mark tells the story of Jesus' encounter with a demon-possessed man. He lived a life in darkness living in a culture which did not know God while being possessed by demons. The community rejected the man, but not Jesus. Christians today can easily dismiss many in the World. But we need to be careful to practice Jesus' mercy.
