Mark 16:14-17

Still later he appeared to the eleven disciples as they were eating together. He rebuked them for their stubborn unbelief because they refused to believe those who had seen him after he had been raised from the dead. And then he told them, “Go into all the world and preach the Good News to everyone. Anyone who believes and is baptized will be saved. But anyone who refuses to believe will be condemned. These miraculous signs will accompany those who believe: They will cast out demons in my name, and they will speak in new languages.
