Mark 16:15, 17-18, 20

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

And these signs will accompany those who believe: In my name they will drive out demons; they will speak in new tongues; they will pick up snakes with their hands; and when they drink deadly poison, it will not hurt them at all; they will place their hands on sick people, and they will get well.”

Then the disciples went out and preached everywhere, and the Lord worked with them and confirmed his word by the signs that accompanied it.
