28 "Then, after doing all those things, I will pour out my Spirit upon all people. Your sons and daughters will prophesy. Your old men will dream dreams, and your young men will see visions. 29 In those days I will pour out my Spirit even on servants-men and women alike. 30 And I will cause wonders in the heavens and on the earth- blood and fire and columns of smoke. 31 The sun will become dark, and the moon will turn blood red before that great and terrible day of the Lord arrives. 32 But everyone who calls on the name of the Lord will be saved, for some on Mount Zion in Jerusalem will escape, just as the Lord has said. These will be among the survivors whom the Lord has called.

Commentary on Joel 2:28-32
(Read Joel 2:28-32)
The promise began to be fulfilled on the day of Pentecost, when the Holy Spirit was poured out, and it was continued in the converting grace and miraculous gifts conferred on both Jews and Gentiles. The judgments of God upon a sinful world, only go before the judgment of the world in the last day. Calling on God supposes knowledge of him, faith in him, desire toward him, dependence on him, and, as evidence of the sincerity of all this, conscientious obedience to him. Those only shall be delivered in the great day, who are now effectually called from sin to God, from self to Christ, from things below to things above.
