Mark 16:14-16

14Afterwards as they lay at table he was manifested to the eleven, and reproached [them with] their unbelief and hardness of heart, because they had not believed those who had seen him risen.

15And he said to them, Go into all the world, and preach the glad tidings to all the creation.

16He that believes and is baptised shall be saved, and he that disbelieves shall be condemned.
