Mark 16:15-18

And He said to them, Go into all the world and preach and publish openly the good news (the Gospel) to every creature [of the whole human race]. He who believes [who adheres to and trusts in and relies on the Gospel and Him Whom it sets forth] and is baptized will be saved [from the penalty of eternal death]; but he who does not believe [who does not adhere to and trust in and rely on the Gospel and Him Whom it sets forth] will be condemned. And these attesting signs will accompany those who believe: in My name they will drive out demons; they will speak in new languages; They will pick up serpents; and [even] if they drink anything deadly, it will not hurt them; they will lay their hands on the sick, and they will get well.
