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.[c] Joel 2:28-32
