"Many today write and speak as if the only purpose in following Jesus were to find complete personal fulfilment and satisfaction, to follow a way or path of personal spirituality which will meet our felt needs. That is hardly the point. There's a war on. God is at work in our world; so are the forces of evil; and there really is no time or space for self-indulgent spiritualities that shirk the slightest personal cost, or even resist it on the grounds that all the desires and hopes one finds within one's heart must be God-given so must be realized."
(Extract from commentary on Mark 9.38-50 in 'Mark For Everyone' by Bishop Tom Wright)
