17 "In the last days, God says, it shall come to pass that I will pour out my Spirit upon all mankind; "Your sons and your daughters shall prophesy, your young men shall see visions, your old men shall dream dreams;
18 upon my slaves, both men and women, in those days, will I pour out my Spirit, and they shall prophesy.
19 In the sky above I will show marvels, And signs in the earth beneath; Blood and fire, and vapor of smoke.
20 Into darkness shall the sun be turned, And into blood the moon, Ere the day of the Lord come, that great and terrible day.
21 And every one who calls upon the name of the Lord will be saved.
