16 No, what you see was predicted long ago by the prophet Joel:
17 ‘In the last days,’ God says,‘I will pour out my Spirit upon all people.Your sons and daughters will prophesy.Your young men will see visions,and your old men will dream dreams.
18 In those days I will pour out my Spiriteven on my servants—men and women alike—and they will prophesy.
19 And I will cause wonders in the heavens aboveand signs on the earth below—blood and fire and clouds of smoke.
20 The sun will become dark,and the moon will turn blood redbefore that great and glorious day of the lord arrives.
21 But everyone who calls on the name of the lordwill be saved.’
22 “People of Israel, listen! God publicly endorsed Jesus the Nazarene by doing powerful miracles, wonders, and signs through him, as you well know.
