Andreas Köstenberger begins by surveying the state of research on mission in the Fourth Gospel, then covers foundational linguistic, definitional, and literary matters. The following two chapters contain the actual study of the missions of Jesus and the disciples. In discussing the disciples' mission, special attention is given to the question of how later generations of disciples should be related to Jesus' original followers.
The volume concludes with a chapter on the implications of Köstenberger's findings for the Fourth Gospel's purpose and for the mission of the contemporary church. Köstenberger engages missiological constructs based on the Fourth Gospel, including the so-called "incarnational model" of mission, and concludes that this model is seriously flawed and should be replaced by a "representational model" of mission that views Jesus' followers as his representatives, who do not share in the theologically unique aspects of his incarnation.
