Acts 2:37-39 (ESV):
37 Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, “Brothers, what shall we do?” 38 And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit. 39 For the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself.”
Some interpret verse 39 as saying that the gift of the Holy Spirit was promised specifically for Peter's audience, their children, and contemporary people who were far off at the moment. Essentially, the first-century Church. Would that interpretation be accurate?
Addendum - Examples of how the gift of the Holy Spirit was received in the New Testament:
Acts 2:1-4 (ESV):
When the day of Pentecost arrived, they were all together in one place. 2 And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. 3 And divided tongues as of fire appeared to them and rested on each one of them. 4 And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
Acts 5:32 (ESV):
32 And we are witnesses to these things, and so is the Holy Spirit, whom God has given to those who obey him.”
Acts 8:14-20 (ESV):
14 Now when the apostles at Jerusalem heard that Samaria had received the word of God, they sent to them Peter and John, 15 who came down and prayed for them that they might receive the Holy Spirit, 16 for he had not yet fallen on any of them, but they had only been baptized in the name of the Lord Jesus. 17 Then they laid their hands on them and they received the Holy Spirit. 18 Now when Simon saw that the Spirit was given through the laying on of the apostles' hands, he offered them money, 19 saying, “Give me this power also, so that anyone on whom I lay my hands may receive the Holy Spirit.” 20 But Peter said to him, “May your silver perish with you, because you thought you could obtain the gift of God with money!
Acts 9:17-19 (ESV):
17 So Ananias departed and entered the house. And laying his hands on him he said, “Brother Saul, the Lord Jesus who appeared to you on the road by which you came has sent me so that you may regain your sight and be filled with the Holy Spirit.” 18 And immediately something like scales fell from his eyes, and he regained his sight. Then he rose and was baptized; 19 and taking food, he was strengthened.
Acts 10:44-47 (ESV):
44 While Peter was still saying these things, the Holy Spirit fell on all who heard the word. 45 And the believers from among the circumcised who had come with Peter were amazed, because the gift of the Holy Spirit was poured out even on the Gentiles. 46 For they were hearing them speaking in tongues and extolling God. Then Peter declared, 47 “Can anyone withhold water for baptizing these people, who have received the Holy Spirit just as we have?”
Acts 19:1-7 (ESV):
And it happened that while Apollos was at Corinth, Paul passed through the inland country and came to Ephesus. There he found some disciples. 2 And he said to them, “Did you receive the Holy Spirit when you believed?” And they said, “No, we have not even heard that there is a Holy Spirit.” 3 And he said, “Into what then were you baptized?” They said, “Into John's baptism.” 4 And Paul said, “John baptized with the baptism of repentance, telling the people to believe in the one who was to come after him, that is, Jesus.” 5 On hearing this, they were baptized in the name of the Lord Jesus. 6 And when Paul had laid his hands on them, the Holy Spirit came on them, and they began speaking in tongues and prophesying. 7 There were about twelve men in all.
2 Timothy 1:6-7 (ESV):
6 For this reason I remind you to fan into flame the gift of God, which is in you through the laying on of my hands, 7 for God gave us a spirit not of fear but of power and love and self-control.
