In John chapter 20, after His resurrection, Jesus appears to Mary. She's distraught and thinks that His body has been stolen. She's is great emotional turmoil and can't even think straight. It's so bad that she mistakes Him for the gardener.
Well, interestingly, Jesus asks her, "Woman, why are you crying?" On the surface this seems like an odd question to ask since the answer's rather obvious. But Jesus doesn't ask questions for His sake since He already knows. Instead, He asks questions so that we face the obvious about ourselves and our situation - which, alas, we're experts at avoiding. We're all experts at seeing the mistakes of others, right? Well, the Lord often comes and asks us to face a truth we're suppressing, that we won't face.
