28 And it shall come to pass afterward, 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 and also upon the servants and upon the handmaids in those days will I pour out my Spirit. 30 And I will show wonders in the heavens and in the earth: blood, and fire, and pillars of smoke. 31 The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of Jehovah cometh. 32 And it shall come to pass, that whosoever shall call on the name of Jehovah shall be delivered; for in mount Zion and in Jerusalem there shall be those that escape, as Jehovah hath said, and among the remnant those whom Jehovah doth 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.
