27 Then you will know that I am in Israel, that I am the LORD your God, and that there is no other; never again will my people be shamed.

The Day of the LORD

28 “And afterward, I will pour out my Spirit on all people. Your sons and daughters will prophesy, your old men will dream dreams, your young men will see visions.
29 Even on my servants, both men and women, I will pour out my Spirit in those days.
30 I will show wonders in the heavens and on the earth, blood and fire and billows of smoke.
31 The sun will be turned to darkness and the moon to blood before the coming of the great and dreadful day of the LORD.
32 And everyone who calls on the name of the LORD will be saved; for on Mount Zion and in Jerusalem there will be deliverance, as the LORD has said, even among the survivors whom the LORD calls.a
