The Barrd said:
The Ephesians in Acts 19 had been baptized by John the Baptist, for the remission of sin. John was preaching about the One Who would come after him, Who would baptize with the Holy Spirit and with fire.
When they were told about this, the Ephesians were baptized in the Name of Jesus Christ And that is when they received the Holy Spirit.
It doesn't matter who they were baptized by and as a matter fact Jesus never baptized anybody, but v1 says they were disciples of Jesus and v2 says they believed. Paul only questioned if they had received the baptism of the Holy Spirit and not whether or not they were really saved.
The point is that when they said they didn't know that there was a holy spirit to be saved he laid hands on them and they receive the Holy Spirit and spoke in tongues AND prophesied, just as the 11 did in Acts 2:4, unless you don't think they were saved either? v5 shows they were baptized in water and v6 shows that they were baptized in the Holy Spirit spoke in tongues when Paul laid his hands on them. You will note also if you care to that in Acts 10 Peter was commanded to speak to Cornelius and his household, who were already believers, so he did, and while doing so they received the baptism of the Holy Spirit and afterwards received water baptism. In both cases the baptism of the Holy Spirit follows salvation and is not part of the initial confession of salvation. You will also note here than in v46, Luke notes that they were baptized in the Holy Spirit which was evident because they spoke in tongues. Clearly the baptism of the Holy Spirit, with the initial evidence of speaking in tongues, follows salvation.
