What does John 20:5 mean?
John has rushed to Jesus' grave (John 20:1–4). He has come thanks to Mary Magdalene's report that the tomb has been opened and the body is no longer there. Along with Peter, he arrives at the grave site, though John is faster and gets there first. John does not include details about the Roman security team (Matthew 27:62–66), but the men might already be gone (Matthew 28:11).Rather than going in, John crouches down to look inside. Whether this is out of fear, or respect, we're not sure. What he sees inside will not make sense at first. From outside, John can see the strips of linen which were used to wrap Jesus' body (John 19:40). This is likely a confusing sight: John would likely wonder why the grave clothes were left behind, but the body taken away. It won't be until John notices another detail, described in the next verse, that his mind snaps to the truth: Jesus is alive (John 20:7–8).
John 20:1–10 includes the first moments in which Jesus' followers realize He has been resurrected. Mary Magdalene brings Peter and John to the grave after finding it open. John sees the empty grave wrappings and realizes what has happened. Mary will remain behind and encounter a pair of angels, as well as Jesus, soon after. John's chosen details complement those found in Matthew 28:1–10, Mark 16:1–8, and Luke 24:1–12.
Peter and John get a report from Mary Magdalene that Jesus' body is gone. They arrive to find an open grave, and empty grave clothes, along with a folded face cloth. When the two men leave, Mary remains and suddenly encounters a resurrected Jesus. Though she tells the others, they resist believing until they see Jesus in person. Thomas is especially stubborn, and Jesus remarks on how blessed they are to have been given so much proof. John points out that his writing is meant to prove that Jesus is the Messiah, arranged to encourage those who read to come to faith.
