Okay, now I cannot remember if I've already posted the following, in this thread yet:
[quoting my post... about Joel 2/Acts 2]
Here's what I believe about the Joel 2 passage...
I believe when Peter said "THIS is that," that he spoke in specific reference to that which the others "saw" [and heard] that day (and which they had made specific comment in reference to), but not to the entire text he quoted (and I base this on what he then goes on to say further in Acts 3). Here's a commentary I fairly agree with, on this (with my comments below that, in the brackets and that which follows):
[quoting Wm Kelly commentary]
"As usual [speaking of the context of those persons in Acts 2], men arrange themselves in more than one class, some astonished, others hostile and scornful. Peter takes the lead in explaining with gravity and distinctness. He explicitly denies the unworthy thought of intoxication, which the early hour itself should have silenced as against God-fearing souls. It was really what Joel spoke of: not of course the fulfilment as it is to be in the last days, but an effusion of that nature. Indeed, the words of the prophet went in this beyond what that day saw accomplished; for 'all flesh' cannot fairly be limited to Israel, and God, Who was soon about to bring in Gentiles to the name of Christ, will bless the nations in the future kingdom, when all the ends of the world shall remember and turn unto the Lord, and all the kindred of the nations shall worship before Him [Daniel 7:27 (following the specific time period of v.25 [see also vv.20-21])]. The gospel now makes good the indiscriminate grace of God even more profoundly than will be under His future government, when He will show that the kingdom is Jehovah's, and that He is the governor among the nations.
"In the latter day, when Joel's words will be fulfilled as a whole, the Spirit will be poured out, and if Israel enjoy the blessing freely, it will flow far beyond their narrow limits. God's ways will then be known upon earth, His saving health among all nations. Temporal blessing is then to be vouchsafed to Israel (Joel 2:19-27), and their great northern enemy is to be for ever disposed of, for Jehovah will do great things for His people and land, whatever the enemy may have prepared to do. 'My people', He says emphatically, 'shall never be ashamed.' Then as a distinct intimation the prophet [Joel] presents two announcements: the first, the outpouring of the Holy Spirit (vers. 28, 29); the second, external signs of judgment ushering in the days of Jehovah, the circumstances of which are detailed in Acts 3, till we come down to the closing account of their blessings once more. As the wonders above and below precede that day, so does the repentance of Israel prepare for their deliverance and blessing, and especially for the gift of the Spirit. We see the same principle here also.
"For God, in pouring out of His Spirit now, does thereby associate believers with Christ exalted on high. Given in virtue of redemption the Holy Spirit sheds the love of God in their hearts, seals them for the day of redemption, and is the earnest of their inheritance. He dwells in them now, and will quicken their mortal bodies soon at Christ's coming. Besides, He is the blessed and divine bond, constituting them Christ's body and God's house. [...]"

Acts 3:21 [speaking to "ye men of Israel," v.12 (unsaved persons as noted in v.13-15,17,19)] then states: "whom indeed it behooves heaven to receive until the times of restoration of all things of which God spoke by the mouth of His holy prophets from the age." [in contrast to that which He had heretofore kept "hidden in God"/was as of yet undisclosed]
In vv.13 and 26 the phrase "His Servant Jesus" (they had not been expecting the "suffering servant" aspects of His Person, only the "reigning-in-power King" aspects, though both aspects had been prophesied in the OT); and...
...there are TWO "raise" senses spoken of in Acts 3... v.15 speaking of His being "raised from the dead," but the other being "raised" to a position of prominence BEFORE His death (that is, to the position of 'a Prophet like unto Moses'...'raise up unto you of your brethren like unto me [Moses]; him shall ye hear in all things whatsoever he shall say unto you' and 'UNTO YOU FIRST God, having raised up [to a position of prominence BEFORE His death] His Servant Jesus, SENT him to bless you, in turning away every one of you from his iniquities'). The "ALL things which God spoke by the mouth of His holy prophets" (meaning, OT prophecies) have not yet been fully fulfilled, but remain for a yet-future time (and I believe Joel is one such prophecy).
The word "King" is only used [re: Jesus] TWO times in all of the epistles, and both of them are "future" [see Rev19:15b still speaking in "future tense"], 1Tim6:15 being one of those, says, "which IN HIS TIMES He SHALL SHEW [openly manifest], who is the blessed and only Potentate, the King of kings, and Lord of lords"

____________
In Acts 3, Peter is just pointing out how they missed/overlooked the "suffering servant" aspects, he wasn't [in Acts 2] saying all is fulfilled (or soon-to-be) [in the Acts 2 events, there]
