Mark 16:14-18

14Later, Jesus appeared to the eleven [disciples] themselves as they were reclining at the table; and He called them to account for their unbelief and hardness of heart, because they had not believed those who had seen Him after He had risen [from death].

15And He said to them, “Go into all the world and preach the gospel to all creation.

16He who has believed [in Me] and has been baptized will be saved [from the penalty of God’s wrath and judgment]; but he who has not believed will be condemned.

17These signs will accompany those who have believed: in My name they will cast out demons, they will speak in new tongues;

18they will pick up serpents, and if they drink anything deadly, it will not hurt them; they will lay hands on the sick, and they will get well.”
