Details:
There are instances in the Bible, when after Jesus was crucified, his disciples didn't recognize him. One is in John, when Mary is weeping outside of his tomb, and mistakes him for the gardener. (John 20).
Another is in Luke, where 2 of his disciples are on the road to Emmaus (Luke 24), and Jesus joins them, and is talking to them, and asking them why they are so sad, and they do not recognize him as Jesus at first.
What is the significance of them not recognizing Jesus? Why did they not recognize him right away?
Thanks for your answers!
