Dr Tripp Fuller, author, theologian and host of Homebrewed Christianity joins Peter, Sue and Dom from Edinburgh to talk about the big question of who is the one we call Jesus the Christ. What did God do in Christ that we couldn't do for ourselves? Tripp's latest book, Divine Self-Investment, explores an answer to that question that refuses to be confined to simplistic formulae but finds a place in our evolving, relational experience of life, insisting on a God "who is at least as nice as Jesus".
