The title of this book, taken from John 1:14, is normally taken to refer to the notion of 'incarnation', which understands 'the word' as a pre-existent Son of God and 'becoming flesh' as the transformation of this 'word' from a heavenly, divine existence to the life of a human being. Against this conventional interpretation the author argues that John's use of the term 'word' really does refer to an act of speaking, God's expression of His will, and that 'becoming flesh' describes the realisation or embodiment of His intentions, from creation onward, in a form perceptible to human senses, not only in the 'flesh' of Jesus but also in historical reality in the world of men. This has implications for other aspects of John's Gospel, including its historicity, its literary form, and its relationship to the Old Testament, and leads to very different conclusions about the central issue in John's Gospel, the person of Jesus and his relationship to God the Father and to those who believe in him.
