At the centre of the gospel of Mark we find perhaps the most penetrating question one could be asked. About himself, Jesus asked, ‘Who do you say I am?’ Understanding who Jesus is and why he came is the foundational question for all of life. Jesus is either who he says he is, the powerful Son of God, or he is a charlatan who should be condemned. In this account Jesus reveals who he is, his mission to the world, and the subsequent call he makes on the lives of people.
