Mark 16:14-17

Later Jesus showed himself to the eleven apostles while they were eating, and he criticized them because they had no faith. They were stubborn and refused to believe those who had seen him after he had risen from the dead. Jesus said to his followers, “Go everywhere in the world, and tell the Good News to everyone. Anyone who believes and is baptized will be saved, but anyone who does not believe will be punished. And those who believe will be able to do these things as proof: They will use my name to force out demons. They will speak in new languages.
