17 And it shall come to pass in the last days, says God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:

18 And on my servants and on my handmaidens I will pour out in those days of my Spirit; and they shall prophesy:

19 And I will show wonders in heaven above, and signs in the earth beneath; blood, and fire, and vapor of smoke:

20 The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord comes:

21 And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
