Joel 2:28-32 "And it shall come to pass afterward, that I will pour out my Spirit on all flesh; your sons and your daughters shall prophesy, your old men shall dream dreams, and your young men shall see visions. Even on the male and female servants in those days I will pour out my Spirit. And I will show wonders in the heavens on the earth, blood and fire, and columns of smoke. The sun shall be turned to darkness, and the moon to blood, before the heat and awesome day of the LORD comes. And it shall come to pass that everyone who calls on the name of the LORD shall be saved. For in Mount Zion and Jerusalem there shall be be those who escape, as the LORD has said, and among the survivors be those whom the LORD calls."
