No, you are mistaken. Peter's recital of Joel 2:28-32 is only PARTIALLY fulfilled. This was intentional of course.
Joel 2:28 & 29 WERE being fulfilled then and there, yes. Because these are and were then the "LAST DAYS".
But 30-32 have yet to occur. Obviously. These doings are to happen as prophesied in Revelation chapters 6 thru 19 et al.
Another thought....both here AND in Acts 15, there embedded in the recitation of OT prophecies is the consolation to the hearers of the SURETY of the reconstitution of the Nation Israel in the promised Kingdom.
Joe 2:30
And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.
Joe 2:31
The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.
Joe 2:32
And it shall come to pass,
that whosoever shall call on the name of the LORD shall be delivered:
for in mount Zion and in Jerusalem shall be deliverance, as the LORD hath said, and in the remnant whom the LORD shall call.
The a-mills, post-mills and historists mess up badly with this verse. Because they don't "get it" for lack of a better term.
