Mark 16:14-18

14Afterward he appeared to the eleven as they sat eating, and upbraided them with their unbelief and hardness of heart, because they believed not them who had seen him after he was risen.1 15And he said to them, Go ye into all the world, and preach the gospel to every creature. 16He that believeth and is baptized shall be saved; but he that believeth not shall be damned. 17And these signs shall follow them that believe; In my name shall they cast out demons; they shall speak in new tongues; 18They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
