17 ‘In the last days, God says,I will pour out my Spirit on everyone. Your sons and your daughters will prophesy,your young men will see visions,and your old men will dream dreams.

18 In those days I will even pour out my Spiriton my slaves, men and women alike,and they will prophesy.

19 I will work wonders in the sky aboveand signs on the earth below:blood, fire, and clouds of smoke.

20 The sun will turn to darkness,and the moon to blood,before the coming of the great and glorious Day of the Lord.

21 Then whoever calls on the name of the Lordwill be saved.’
