In Happy New Year, Charlie Brown one of the Peanuts TV specials, Charlie Brown tells Lucy that next year he is going to be a changed person. "Oh, be serious, Charlie Brown," Lucy says. Charlie protests, "No, I mean it. I am going to be strong and firm." "Forget it, Charlie Brown," Lucy tells him. "You will always be wishy-washy." Charlie ponders, "Why can't I change just a little bit? I've got it! I'll be wishy one day, washy the next."
In today's Gospel, Jesus tells his disciples there is no room for being wishy-washy. A follower will have no place to rest his head. Disciples must abandon their former lives to proclaim the kingdom of God. Jesus says that it they look back, they are not fit to preach the kingdom.
