John

Summary of the Book of John

Written: c. AD 85–95

John states his purpose outright: "these are written, that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name" (20:31). Traditionally attributed to the apostle John, "the disciple whom Jesus loved," the fourth Gospel is built not on parables but on seven signs, from water turned to wine at Cana to Lazarus raised at Bethany, each paired with extended discourse. Its prologue reaches back before Genesis: "In the beginning was the Word... and the Word became flesh and lived among us."

Chapters 1–12, often called the Book of Signs, track rising belief and rising hostility as Jesus makes the seven "I am" claims — bread of life, light of the world, door, good shepherd, resurrection and the life, way and truth and life, true vine — and finally "Before Abraham came into existence, I AM," at which his hearers take up stones. Chapters 13–17 slow to a single evening: Jesus washes the disciples' feet, gives the new commandment to love one another, promises the Holy Spirit as Counselor, and prays for the unity of all who will believe through the apostles' word.

In John the cross is not defeat but glory — the "hour" toward which everything moves, announced by the Baptist at the start: "Behold, the Lamb of God, who takes away the sin of the world." The passion account runs to Thomas's climactic confession, "My Lord and my God," the highest human statement about Jesus in any Gospel. An epilogue by the Sea of Galilee restores Peter with three questions matching his three denials — showing that believing, in John, always issues in following.

Written so that readers may believe that Jesus is the Christ, the Son of God, and by believing have life in his name.
