That's what the angel asked Mary Magdalene as she stood weeping outside Jesus' tomb.
Today I was praying with this Gospel, and I tried to do what St Ignatius recommends: imagine the scene, picture the details and imagine everything that went on. Mary Magdalene is a saint of the Church, but at that moment she was a bereaved woman crying over the death of someone she dearly loved.
She became a saint because of her relationship with Jesus. She probably didn't do anything special in terms of doing anything outstanding or heroic. But she loved Jesus. She loved him with a chaste, pure love, and she let his love for her transform her heart and actions. We can do that too!
