John Trapp on Joel 2:28

Verſe 28. And it ſhall come to paſſe afterwards] ſc. In the dayes of the Meſſiah (which is called the world to come Heb. 2.5.) but eſpecially after his Aſcenſion: ſee Ioh. 7.37. Act. 2, where this propheſie was fulfilled, and this place taken for the firſt text preached on by the Apoſtles, verſe. 17. to the converſion of three thouſand ſoules at one ſermon. For together with the word there went forth a power, Luk. 7. 2 Tim. 1.7. even that Spirit of power, of love, and of a ſound mind, here promiſed to be powred out, not diſtilled only (ſee the Note on Zech. 12.10.) and that upon all fleſh. Spirit upon fleſh, the beſt thing upon the baſeſt: yea upon all fleſh, without reſpect of perſons, or difference made of ſex, age, or condition: provided that they know and acknowledg themſelves to be but fleſh Gen, 6.3. corrupt and carnal (animas etiam incarnavimus, Bern. as an Ancient complaineth) and that whatſoever is of the fleſh is fleſh. Ioh. 3.6. (for who can bring a clean thing out of an unclean?) that whole Man is in evill, and whole evill in Man; neither can it be gotten out in any meaſure, till the heart be mollified and made tender as fleſh Ezeh. 11.19. and 36.26, 27. which cannot be done till men be taught of God, and drawn out of darkneſſe into his marvelous light: till they be ſpiritualized,2 Cor. 3.18. and transformed into the ſame image from glory to glory as by the ſpirit of the Lord.

and your ſons and your daughters ſhall propheſie] This was fulfilled Act. 2. as St. Peter ſheweth. For the new Teſtament is but the old unfolded and fulfilled: as was alſo typified in the two Cherubims of the ſanctuary, looking intently into the Propitiatory (Chriſt Rom. 3.25.) but with their faces turn'd one towards another Exod. 25.20. See Act. 26.22. It was fulfilled, I ſay, in that viſible deſcenſion of the holy Ghoſt upon the Apoſtles and the reſt Act. 2. Act. 8.15, 17. and 10.44. So that this makes nothing at all for the Enthuſiaſts raptures and dotages: the true offpring they are,Funcc. Chronol. of thoſe ancient Euchites or Meſſalanii, who, leaving their trades, gave themſelves to much ſleep, and called their dreams and phantaſies propheſies, Anno Dom. 371.

your old men ſhall dream &c. your yong men ſhall ſee viſions] i. e. God will no leſs open his will unto them then he did of old to the Prophets by dreams and viſions: for, by the conduct of the Spirit, they ſhall be led into all truth and holineſſe: they ſhall be all a royall Prieſthood 1 Pet. 2.5. Rev. 1.6. full of all goodneſſe, filled with all knowledge, able alſo to admoniſh one another Rom. 15.14.
