a very brave or very foolish sheep

Matthew 10:16-20

Jesus uses a word picture of a sheep going out among the wolves. I have to work really hard to picture this. i can picture a wolf coming in among the sheep but that's not what Jesus tells us to picture. He tells us to picture a field full of wolves and a sheep walking through them. Jesus uses a lot of animals in this paragraph: sheep, wolves, doves, snakes. Jesus also includes a list of what the disciples can look forward to: arrest, flogging, trials. Even though they were not to go to the Gentiles at this time, they would attract the attention of the Gentile rulers and would be brought before their courts. Jesus tells his disciples to not worry about preparing a defense but to just speak as they are lead by the Spirit.
This all go against common sense: you don't send sheep out to combat wolves and you don't leave your trials to "chance". However, it fits completely with what Jesus had instructed his disciples to do so far: go on a journey but don't take any money or clothes besides what they are wearing. Again, against all common sense.
I wonder if Christians have taken on the characteristics of the wolf. I wonder if we have tried to fight fire with fire as a group. I wonder what it would mean for me to go as an innocent but shrewd sheep. Sheep are pretty vulnerable and humble animals. It would force me to rely completely on Jesus for protection and guidance. Do I dare?
