Joel 2:28-32

“After that, I will pour out my Spirit on all people. Your sons and daughters will prophesy. Your old men will have dreams. Your young men will have visions. In those days I will pour out my Spirit on those who serve me, men and women alike. I will show wonders in the heavens and on the earth. There will be blood and fire and clouds of smoke. The sun will become dark. The moon will turn red like blood. It will happen before the great and terrible day of the LORD comes. Everyone who calls out to me will be saved. On Mount Zion and in Jerusalem some of my people will be left alive. I have chosen them. That is what I have promised.
