Acts 2:17-21

17 And in the last days it shall be, God declares, that I will pour out my Spirit on 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 even on my male servants and female servants in those days I will pour out my Spirit, and they shall prophesy.19 And I will show wonders in the heavens above and signs on the earth below, blood, and fire, and vapor of smoke;20 the sun shall be turned to darkness and the moon to blood, before the day of the Lord comes, the great and magnificent day.21 And it shall come to pass that everyone who calls upon the name of the Lord shall be saved.
