16. But [instead] this is [the beginning of] what was spoken through the prophet Joel:
17. And it shall come to pass in the last days, God declares, that I will pour out of My Spirit upon all mankind, and your sons and your daughters shall prophesy [telling forth the divine counsels] and your young men shall see visions (divinely granted appearances), and your old men shall dream [divinely suggested] dreams.
18. Yes, and on My menservants also and on My maidservants in those days I will pour out of My Spirit, and they shall prophesy [telling forth the divine counsels and predicting future events pertaining especially to God's kingdom].
19. And I will show wonders in the sky above and signs on the earth beneath, blood and fire and smoking vapor;
20. The sun shall be turned into darkness and the moon into blood before the obvious day of the Lord comes–that great and notable and conspicuous and renowned [day].
21. And it shall be that whoever shall call upon the name of the Lord [invoking, adoring, and worshiping the Lord–Christ] shall be saved. [Joel 2:28-32.]
