A stone rolled away and an empty tomb, Christianity distinguishes itself from every other religion in that its leader died but did not remain dead. Find the tomb of Jesus with a body still inside and you destroy the religion. Christianity could have been snuffed out within days by both Roman and Jewish leaders but it was not. Because the stone had been rolled away and the tomb was empty.
"To the Jews who had believed him, Jesus said, 'If you hold to my teaching, you are really my disciples. Then you will know the truth, and the truth will set you free.'" John 8:31-32
