What's in a name?

This past weekend we celebrated "Jesus' Birthday" at the church and ended the event with an impromptu Christmas Pageant. Annaka wanted to be an angel (because they got to wear the wings) and tell everyone about the good news. Tonight Annaka and I were reading the story of the Nativity before bed. We came to the part where the angel comes to Mary and says that she will have a baby and that she will name him Jesus when Annaka asked me, "How did you know what my name was when I came out of your belly?" I said that an angel told me too.
