Many people who are insane can still act normal while collecting huge crowds of followers. So how does one know that Jesus wasn't one of these people? Well, when looking at the insane, we often see that they are emotionally imbalanced, have fits of anger, depression, or anxiety. But when we look at Jesus, we don't see any of this. We see Him weeping at Lazarus' death, which is completely normal, because anyone weeps when someone close to them dies. John 11:34-35 says: "He said, 'Where have you laid him?' They said to Him, 'Lord, come and see.' Jesus wept."
