The error here, which I believe is also not understood by even Charismatics is this. The gift OF the Holy Spirit or the Promise OF the Holy Spirit is NOT the Holy Spirit. The promise is power from/OF the Spirit being manifested through disciples. That is the contextual understanding of verse 33
ACT 2:33 Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this which you see and hear.
What was 'seen and heard' was supernatural power being manifested from the Holy Spirit and 'through' the disciples. The PROMISE FROM the Father and Holy Spirit was always holy spirit power not the Holy Spirit person.
Jesus prophesied what would be received FROM the Holy Spirit in Luke with no mention of 'the Holy Spirit' from which it would come.
LUK 24:49 And behold, I send the promise of my Father upon you; but stay in the city, until you are clothed with power from on high."
The promise of the Father wasn't 'the Father', it was a promise of 'power' which would be poured out FROM the Holy Spirit on His church, on the day of Pentecost.
Jesus confirmed this promise issue again.
ACT 1:4 And, being assembled together with them, commanded them that they should not depart from Jerusalem, but wait for the promise of the Father, which, saith he, ye have heard of me.
Were these apostles saved/born again when Jesus was talking to them? YES! Had they probably been baptized 'correctly' in accordance to the mandate from Jesus at His accession by this time, if not before? I'm going to assume so. If that's what gets people the Holy Spirit living in them, as most or all believe here (both 'haves' and have nots') then why didn't the disciples have HIM?
