17 And it will come about, in the last days, says God, that I will send out my Spirit on all flesh; and your sons and your daughters will be prophets, and your young men will see visions, and your old men will have dreams:
18 And on my men-servants and my women-servants I will send my Spirit, and they will be prophets.
19 And wonders will be seen in heaven, and signs on the earth, blood and fire and smoke:
20 The sun will become dark and the moon will be turned to blood, before that great day of the Lord comes in glory:
21 And whoever makes his prayer to the Lord will have salvation.
