Nearly all metaphors in the Gospel according to John relate to ancient family imagery. Thus, the disciples are born of the Father; the Father provides them with bread and drink (water); He educates them and protects them and a dwelling is prepared for them, and so on. This family imagery, which is interwoven throughout the Gospel in a complex network, provides a key to the understanding of the message of the Fourth Gospel. In this volume, after exploring numerous state-of-the-art theories on metaphor, a customised metaphor theory is developed from the Fourth Gospel itself, which can be applied to the analysis of the Gospel as a whole. The theory is based on two of the best-known metaphors in the Fourth Gospel: I am the Good Shepherd, and I am the True Vine. Subsequently, all other metaphors are analysed according to this theory.
