** [But] later, as the eleven were at table, he appeared to them and rebuked them for their unbelief and hardness of heart because they had not believed those who saw him after he had been raised.
** He said to them, “Go into the whole world and proclaim the gospel to every creature.
Whoever believes and is baptized will be saved; whoever does not believe will be condemned.
These signs will accompany those who believe: in my name they will drive out demons, they will speak new languages. They will pick up serpents [with their hands], and if they drink any deadly thing, it will not harm them. They will lay hands on the sick, and they will recover.”
