Mark 16:15-18

He told them, “Go into all the world and proclaim the Good News to every creature. He who believes and is immersed shall be saved, but he who does not believe shall be condemned. These signs will accompany those who believe: in My name they will drive out demons; they will speak new languages; they will handle snakes; and if they drink anything deadly, it will not harm them; they will lay hands on the sick, and they will get well.”
