Jesus said to his disciples:
"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 lay hands on the sick,
and they will recover."

So then the Lord Jesus,
after he spoke to them,
was taken up into heaven
and took his seat at the right hand
of God.

But they went forth and preached everywhere,
while the Lord worked with them
and confirmed the word
through accompanying signs.
