The gifts are the manifestataion of the Holy Spirit!
We have an example of the Holy Spirit without "gifts";
Luke 2:25-27 And, behold, there was a man in Jerusalem, whose name was Simeon; and the same man was just and devout, waiting for the consolation of Israel: and the Holy Ghost was upon him. And it was revealed unto him by the Holy Ghost, that he should not see death, before he had seen the Lord's Christ. And he came by the Spirit into the temple: and when the parents brought in the child Jesus, to do for him after the custom of the law,
We have the promise of the indwelling Holy Spirit;
John 15:26 But when the Comforter is come, whom I will send unto you from the Father, even the Spirit of truth, which proceedeth from the Father, he shall testify of me:
We have the promise of gifts to the nation of Israel;
Joel 2:28-31 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: And also upon the servants and upon the handmaids in those days will I pour out my spirit. And I will shew wonders in the heavens and in the earth, blood, and fire, and pillars of smoke. The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.
At Pentecost we have a declaration of the fulfillment of this promise;
Acts 2:14-16 But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all ye that dwell at Jerusalem, be this known unto you, and hearken to my words: For these are not drunken, as ye suppose, seeing it is but the third hour of the day. But this is that which was spoken by the prophet Joel;
At Pentecost we have the disciples (Galilaeans) and those who were observing. The promised Holy Spirit came on those who believed and evidence was shown by being able to speak in other languages and the visual indicator of tongues of flame.
Acts 2:3-4 And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
Those who observed heard Peter preach the gospel. Some believed the truth of the gospel and as a result of this were were horrified to now understand that a few weeks earlier they had put to death the Messiah. They called Peter and the disciples "brothers" indicating that they too had become Christian. They asked what they should do.
Acts 2:37-39 Now, having heard this, they were stung to the heart with poignant sorrow. And they said to Peter and the rest of the apostles, What shall we do, men, brothers? And Peter said to them, Have a change of mind, that change of mind being accompanied by abhorrence of and sorrow for your deed, and let each one of you be baptized upon the ground of your confession of belief in the sum total of all that Jesus Christ is in His glorious Person, this baptismal testimony being in relation to the fact that your sins have been put away, and you shall receive the gratuitous gift of the Holy Spirit, for to you is the promise and to your children and to all who are at a distance, as many as the Lord our God shall with a divine summons call to himself. - Wuest
There are many that will argue the point. But I see here that repentance and baptism come after salvation and that the receiving of the Holy Spirit as a gift is different than receiving the Holy Spirit at salvation.
The case can be made that the reception of the Holy Spirit at salvation is distinct from the reception of the "gift" of the Spirit. We can see the distinction with the example of Simon;
Acts 8:13 Then Simon himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done.
We have an example of salvation preceding the reception of the gift of the Holy Spirit and that this reception is accomplished through the laying on of hands.
Acts 8:14-18 Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John: Who, when they were come down, prayed for them, that they might receive the Holy Ghost: (For as yet he was fallen upon none of them: only they were baptized in the name of the Lord Jesus.) Then laid they their hands on them, and they received the Holy Ghost. And when Simon saw that through laying on of the apostles' hands the Holy Ghost was given, he offered them money,
There are three main view of these gifts. That they still function today as they did at the time of the apostles, that only some do, or that none do. It is difficult to support the full gift view since it also included raising the dead. I think the partial (sometimes called administrative gift) view is also difficult to support because there is no laying on of hands and these "gifts" often seem difficult to identify.
The verses in Joel also seem to have not been fulfilled completely just as when Jesus started His ministry, he did not complete the quote from Isaiah. There was room left for Israel to receive the Kingdom that was offered. However even the giving of spiritual gifts to the gentiles was insufficient to provoke the Jews to jealousy.
Acts 10:45 And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
Romans 10:19-20 But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you. But Esaias is very bold, and saith, I was found of them that sought me not; I was made manifest unto them that asked not after me. But to Israel he saith, All day long I have stretched forth my hands unto a disobedient and gainsaying people.
I suspect that when Israel is restored, we will again see these gifts of power spoken of by Joel.
