In this Gospel, the accent is on disbelief and doubt.  The women who first went to the tomb were afraid to tell anyone what they had encountered, even though the young man in a white robe had told them that Jesus was risen.  In the longer version of the chapter (Mark 16), the details are markedly different but the outcome is the same.  Mary Magdalene did report what she saw but no one believed her.  Then, Jesus appeared to a couple of people who subsequently told his disciples and other followers.  But they were disbelieved, too.  Finally, Jesus appeared to the eleven disciples but had to scold them for being hard-hearted and lacking belief.  Jesus then admonished them to preach the gospel, which would be accompanied by a number of dubious signs.
