Their day of Pentecost empowerment came.
Christians (at least some of us) are waiting for OUR day of Pentecost empowerment.
"but those who wait upon the Lord
shall renew their strength; ............"
Who does “they” refer to?
The baptism with the Holy Spirit is for all those who believe, not just for those who were in Jerusalem on the day of Pentecost.
- For the promise is to you and to your children, and to all who are afar off, as many as the Lord our God will call.” Acts 2:39
Believers continued to receive the baptism with the Holy Spirit, many years after that day.
While Peter was still speaking these words, the Holy Spirit fell upon all those who heard the word. And those of the circumcision who believed were astonished, as many as came with Peter, because the gift of the Holy Spirit had been poured out on the Gentiles also. For they heard them speak with tongues and magnify God.
Then Peter answered, “Can anyone forbid water, that these should not be baptized who have received the Holy Spirit just as we have?”
Acts 10:44-47
This was some 10 years after the day of Pentecost.
And it happened, while Apollos was at Corinth, that Paul, having passed through the upper regions, came to Ephesus. And finding some disciples he said to them, “Did you receive the Holy Spirit when you believed?”
So they said to him, “We have not so much as heard whether there is a Holy Spirit.”
And he said to them, “Into what then were you baptized?”
So they said, “Into John’s baptism.”
Then Paul said, “John indeed baptized with a baptism of repentance, saying to the people that they should believe on Him who would come after him, that is, on Christ Jesus.”
When they heard this, they were baptized in the name of the Lord Jesus. And when Paul had laid hands on them, the Holy Spirit came upon them, and they spoke with tongues and prophesied.
Acts 19:1-6
The events of Acts 19 took place around AD 53.
In addition, Jesus said of all those who believe -
And He said to them, “Go into all the world and preach the gospel to every creature. He who believes and is baptized will be saved; but he who does not believe will be condemned. And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues; they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick, and they will recover.” Mark 16:15-18
The power to cast out devils, and heal the sick is promised to those who believe; to those who obey.
And we are His witnesses to these things, and so also is the Holy Spirit whom God has given to those who obey Him.” Acts 5:32
