What is a Christian?

Enjoyed reading 'The Reason for God' - 'Belief in an age of Scepticism'.  One of the things it talks about is what a Christian really is.  The definition Tim Keller (the author) gives is:

'Christians are people who let the reality of Jesus change everything about who they are, how they see, and how they live.'

Oh that I would, and we would as a Church, live out what it means to be a Christian and help people in Crouch End, and the surrounding areas of Haringey, to see Jesus in such a way...
