28 And it shall come to pass afterwards [that] I will pour out my Spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions. 29 Yea, even upon the bondmen and upon the handmaids in those days will I pour out my Spirit. 30 And I will shew wonders in the heavens and on the earth, blood, and fire, and pillars of smoke. 31 The sun shall be changed to darkness, and the moon to blood, before the great and terrible day of Jehovah come. 32 And it shall be that whosoever shall call upon the name of Jehovah shall be saved: for in mount Zion and in Jerusalem shall be deliverance, as Jehovah hath said, and for the residue whom Jehovah shall call.
Matthew Henry's Commentary on Joel 2:28-32
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.
