191 It happened that, while Apollos was at Corinth, Paul, having passed through the upper country, came to Ephesus, and found certain disciples. 2 He said to them, “Did you receive the Holy Spirit when you believed?”
They said to him, “No, we haven’t even heard that there is a Holy Spirit.” 3 He said, “Into what then were you baptized?”
They said, “Into John’s baptism.” 4 Paul said, “John indeed baptized with the baptism of repentance, saying to the people that they should believe in the one who would come after him, that is, in Jesus.” 5 When they heard this, they were baptized in the name of the Lord Jesus. 6 When Paul had laid his hands on them, the Holy Spirit came on them, and they spoke with other languages and prophesied.

Paul, at Ephesus, found some religious persons, who looked to Jesus as the Messiah. They had not been led to expect the miraculous powers of the Holy Ghost, nor were they informed that the gospel was especially the ministration of the Spirit. But they spake as ready to welcome the notice of it. Paul shows them that John never design that those he baptized should rest there, but told them that they should believe on Him who should come after him, that is, on Christ Jesus. They thankfully accepted the discovery, and were baptized in the name of the Lord Jesus. The Holy Ghost came upon them in a surprising, overpowering manner; they spake with tongues, and prophesied, as the apostles and the first Gentile coverts did. Though we do not now expect miraculous powers, yet all who profess to be disciples of Christ, should be called on to examine whether they have received the seal of the Holy Ghost, in his sanctifying influences, to the sincerity of their faith. Many seem not to have heard that there is a Holy Ghost, and many deem all that is spoken concerning his graces and comforts, to be delusion. Of such it may properly be inquired, "Unto what, then, were ye baptized?" for they evidently know not the meaning of that outward sign on which they place great dependence.
