No this is not about the boy band. Actually it is about someone far more important and amazing: Jesus Christ.
As Mark starts out to show us the good news about Jesus, the Messiah, the Son of God, we see a man of amazing authority in his teaching, in his healing power and his ability to cast out demons.
Yet, Jesus is also impressive because he is clear about what he has come to do. He won't be knocked off course, he knows his one direction!
