Discipleship occurs when someone answers the call to learn from Jesus how to live his or her life as though Jesus were living it. The end result is that the disciple becomes the kind of person who naturally does what Jesus did. How the church understands salvation and the gospel is the key to recovering a biblical theology of discipleship. Our doctrines of grace and salvation, in some cases, actually prevent us from creating an expectation that we are to be disciples of Jesus. A person can profess to be a Christian and yet still live under the impression that they don’t need to actually follow Jesus. Being a follower is seen as an optional add-on, not a requirement. It is a choice, not a demand. Being a Christian today has no connection with the biblical idea that we are formed into the image of Christ. In this ground-breaking new book, pastor and author Bill Hull shows why our existing models of evangelism and discipleship fail to actually produce followers of Jesus. He looks at the importance of recovering a robust view of the gospel and taking seriously the connection between conversion—answering the call to follow Jesus—and discipleship—living like the one we claim to follow.

"Touching the Rock" is a unique exploration of that distant, infinitely strange 'other world' of blindness. John Hull writes of odd sounds and echoes, of people without faces, of a curious new relationship between waking and dreaming, of a changed perception of nature and human personality. He reveals a world in which every human experience - eating and lovemaking, playing with children and buying drinks in the bar - is transformed. 'The incisiveness of Hull's observation, the beauty of his language, make this book poetry; the depth of his reflection turns it into phenomenology or philosophy.' Oliver Sacks, neurologist and bestselling author (1933-2015) 'He lets us see with no trace of self-pity or self-praise how blindness has become for him a genuine acquisition, an unforeseeably rich gift that has made of him what so few of us are: excellent watchers and hearers of the world . . . triumphant in the teeth of ruin.' Reynolds Price, American novelist (1933-2011) "Notes on Blindness," a feature film and virtual reality experience by Peter Middleton & James Spinney based on John's original audio diaries. The project is an Archer's Mark Production in association with Fee Fie Foe Films and 104 Films in co-production with Agat Films & Cie/Ex Nihilo. www.notesonblindness.co.uk
