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 Spirit
    even on my servants—men and women alike—
    and they will prophesy.
¹⁹ And I will cause wonders in the heavens above
    and signs on the earth below—
    blood and fire and clouds of smoke.
²⁰ The sun will become dark,
    and the moon will turn blood red
    before that great and glorious day of the Lord arrives.
²¹ But everyone who calls on the name of the Lord
    will be saved.’^[a]

¹⁵ until at last the Spirit is poured out
    on us from heaven.
Then the wilderness will become a fertile field,
    and the fertile field will yield bountiful crops.
