The final chapter of the gospel of John evokes the recent trend of a "post-credits scene" from films. After the main story has been told, John includes one last scene to further add details about what is to come. After Jesus' resurrection and appearances, He meets with the disciples near Galilee. A major outcome of this meeting is Peter's restoration to his former status. No finite work could fully explain Jesus' ministry, so John's eyewitness account is only part of those truths.

Most of Jesus' disciples scattered and hid when He was arrested (Matthew 26:56). Only John and some women were present to see His death and burial (John 19:26–30, 41–42; Matthew 27:60–61). When Jesus' tomb is seen empty, there is further confusion. Jesus appears to His followers, proving that He is alive, and remarking that they are blessed to have so much proof. John will complete his account in the next chapter with another encounter and more reminders about the nature of his writing.

When Jesus was first brought to Pilate, His innocence was obvious (John 18:36–38). However, the mob refuses to be satisfied with anything less than crucifixion. Pilate gives in to these demands. John, who is present for the entire gory spectacle, notes several instances of fulfilled prophecy (Psalm 22:18; Psalm 69:21; Exodus 12:46; Zechariah 12:10). Jesus is then buried in the borrowed tomb of a rich man (Isaiah 53:9) to complete yet another Old Testament prediction. A guard will be posted to ensure no one steals the body (Matthew 27:62–68), which will only serve to confirm that Jesus' eventual resurrection was a true miracle (John 20:1–8).

John's Gospel was written well after the other three, so he frequently chooses to present different details. Chapter 17 detailed Jesus' High Priestly Prayer, just before He entered the garden of Gethsemane. This chapter describes Jesus' arrest, sham trials before Jewish leadership, and the beginning of His trial before the Roman governor. In the following chapter, Jesus will be unfairly condemned, executed, and buried.

Over the last several chapters (John 13—16), Jesus has been giving last-minute instruction to His closest disciples. These lessons composed a large part of the Last Supper. Among those teachings were several warnings about persecution, with the encouragement of knowing the Holy Spirit would come. In chapter 17, we read Jesus' High Priestly Prayer, making requests on behalf of Himself, the apostles, and future believers. After this, Jesus will go into Gethsemane where Judas will turn Him over for arrest and His eventual execution.

This completes the teaching portion of Jesus' words during the Last Supper, begun in chapter 13. Christ echoes many of the themes of His earthly ministry. His focus is especially on encouragement: reminding the disciples that the hard times they will experience will end in victory. While they don't clearly understand, the Holy Spirit will lead them in the right direction. This ends with Christ's beloved declaration that He has "overcome the world." That introduces the record of Jesus' High Priestly Prayer in chapter 17, immediately before His arrest early in chapter 18.

Jesus is in the middle of a long discourse given to the disciples, which began during the last supper. He presents the analogy of a vine and branches, then repeats His command for believers to love each other. Jesus also warns about how the unbelieving world will hate and persecute Christians. This leads into the teachings of chapter 16, which focus on perseverance in the face of trials.

After completing His public ministry in Jerusalem (John 12:36–38), Jesus has washed the feet of the disciples (John 13:3–5), predicted His betrayal (John 13:21), and foreseen Peter's denial (John 13:37–38). Chapter 14 begins a series of remarks meant to encourage the disciples, in the face of dire warnings. Among these are reminders that Jesus is planning to bring them to be where He is, assurance that He is ''the way,'' and the first explicit promises of the coming of the Holy Spirit. Chapter 15 will continue this address, beginning with Jesus' claim to be ''the true vine.'
