The Lord Is Risen the empty tomb, the risen Christ, and the purpose of the book
John 20 is the chapter of resurrection. The stone is gone, the grave-clothes lie undisturbed, and the risen Lord calls Mary by name. He appears to his gathered disciples with peace and a commission, meets doubting Thomas, and draws from him the Gospel's climactic confession — "My Lord and my God!" — before stating why the whole book was written.
Overview of John 20
20:1–18: Mary Magdalene finds the stone removed; Peter and the beloved disciple run to the tomb and find the linen cloths lying and the face-cloth folded by itself — not the work of grave-robbers. The beloved disciple "saw and believed." Mary, weeping, meets the risen Jesus, mistaking him for the gardener until he calls her name; he sends her with the message, "I am ascending to my Father and your Father, to my God and your God."
20:19–31: that evening Jesus appears through locked doors, shows his wounds, gives peace and the commission "as the Father has sent me, so I send you," and breathes on them, "Receive the Holy Spirit." Thomas, absent, demands proof; a week later Jesus meets his need, and Thomas confesses, "My Lord and my God!" — the high-water mark of the Gospel's Christology. John then states his purpose: "these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name."
