What does John 11:40 mean?
Jesus is reassuring Martha by reminding her of their prior conversation (John 11:17–27). Since Martha has spent some time learning from Him (Luke 10:38–42), this may also refer to other teachings she has absorbed. The reason for her doubt is that her brother has been in the grave for four days (John 11:17). For practical and emotional reasons, she's not eager to see the putrid corpse of her loved one (John 11:38–39).From the start of this incident, Jesus arranged various details to set up this very moment. That includes waiting until well after Lazarus has died (John 11:6), arriving only when death was beyond doubt (John 11:17), and allowing a crowd to form (John 11:19; 11:31). The next few verses will show Jesus praying very publicly, specifically so that what happens won't be lost on those who witness it. That fits with the purpose of miracles recorded in the gospel of John: they are "signs" meant to prove Jesus is divine (John 20:30–31).
