Mark 16:14-18

14 Afterward he appeared to the eleven themselves as they sat at table; and he upbraided them for their unbelief and hardness of heart, because they had not believed those who saw him after he had risen.

15 And he said to them, "Go into all the world and preach the gospel to the whole creation.

16 He who believes and is baptized will be saved; but he who does not believe will be condemned.

17 And these signs will accompany those who believe: in my name they will cast out demons; they will speak in new tongues;

18 they will pick up serpents, and if they drink any deadly thing, it will not hurt them; they will lay their hands on the sick, and they will recover."
