Written So That You May Believe

The narrator states that Jesus performed many other signs in the presence of the disciples that are not written in this book. The Gospel therefore presents itself as selective rather than exhaustive. The term sēmeia, 'signs,' links the resurrection appearances with the larger sign structure of the Gospel and underscores that narrated events function as disclosures of Jesus' identity rather than as wonders recorded for their own sake.

Verse 31 gives the purpose of the written selection: 'that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name.' A significant textual variant affects pisteuēte, the present subjunctive, versus pisteusēte, the aorist subjunctive. The former can suggest continuing or deepening belief, while the latter can suggest coming to belief, though the aspectual distinction should not be pressed too rigidly.

The statement summarizes the Gospel's christological and soteriological aims. 'Christ' identifies Jesus as Messiah, while 'Son of God' expresses his unique relation to the Father, and 'life' recalls the prologue and the recurring promise of eternal life throughout the Gospel. Although chapter 21 follows, these verses function as a formal conclusion to the main narrative and provide an interpretive key for the book as a whole.

John 20 narrates the discovery of the empty tomb, appearances of the risen Jesus, the commissioning of the disciples, Thomas's confession, and the Gospel's formal purpose statement. The chapter moves from absence and uncertainty toward recognition and confession. Mary Magdalene first reports the missing body, Peter and the beloved disciple inspect the tomb, Mary encounters Jesus personally, and the gathered disciples receive his peace and mission. Thomas's later encounter then brings the chapter to its christological climax.

The resurrection scenes gather major Johannine themes: seeing and believing, Scripture and understanding, recognition of Jesus' identity, the relation between Father and Son, the gift of the Spirit, and apostolic witness. Jesus' wounds establish continuity between the crucified and risen one, while his appearances transform fearful disciples into commissioned witnesses. The chapter concludes by explaining that the selected signs have been written so readers may believe that Jesus is the Christ, the Son of God, and through believing have life in his name.
