An empty tomb and the Risen Lord!
"On entering the tomb they saw a young man sitting on the right side, clothed in a white robe, and they were utterly amazed.He said to them, “Do not be amazed! You seek Jesus of Nazareth, the crucified. He has been raised; he is not here. Behold the place where they laid him. But go and tell his disciples and Peter, 'He is going before you to Galilee; there you will see him, as he told you.’” - Gospel of Mark 16
