It reveals the laziness of UPCI preaching.
Context.
"Paul... came to Ephesus. There he found some disciples and asked them, “Did you receive the Holy Spirit when you became believers?”
“No,” they answered, “we have not even heard that there is a Holy Spirit.”
“Into what, then, were you baptized?” Paul asked.
“The baptism of John,” they replied.
These men Paul has encountered are clearly disciples of John the Baptist.
Paul explained: “John’s baptism was a baptism of repentance. He told the people to believe in the One coming after him, that is, in Jesus.”
By the looks of things, they were early disciples of John who probably lived in Ephesus, and went back home before the events of the Gospels unfolded: they were proto-Christians ripe for harvest.
On hearing this, they were baptized into the name of the Lord Jesus.
Now these men have become proper disciples- These are actually the verses you would want to point out if you wanted to demonstrate that being a believer does not automatically mean you have received the Holy Ghost... along with acts 8:16.
And when Paul laid his hands on them, the Holy Spirit came upon them, and they spoke in tongues and prophesied. There were about twelve men in all.
