Mark 16:15-20

15 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 disbelieves will be condemned.  17 These signs will accompany those who believe: in my name they will cast out demons; they will speak with new languages;  18 they will take up serpents; and if they drink any deadly thing, it will in no way hurt them; they will lay hands on the sick, and they will recover.”

19 So then the Lord Jesus, after he had spoken to them, was received up into heaven, and sat down at the right hand of God.  20 They went out, and preached everywhere, the Lord working with them, and confirming the word by the signs that followed. Amen.
