"I certainly am immersing you in water following [your] repentance, but the One who follows my [ministry], whose sandals I do not deserve to remove [as His slave], will immerse you people with the Holy Spirit and with fire [i.e., the punishment in hell. See verses

For [Jesus had said, Matt. 3:11], "John immersed you [men] in water but [this time] you will be immersed in the Holy Spirit, and [it will happen] in just a few more days."

And Peter replied, "Every one of you must repent [i.e., change your hearts and lives] and be immersed in the name of Jesus Christ [i.e., by His authority] so that your sins will be forgiven [by God] and then you will receive the gift of the Holy Spirit [to live in your hearts].

Then I remembered what the Lord had said [See 1:4-5]: 'John immersed you [people] in water but you [apostles] will be immersed in the Holy Spirit.'

When they heard this they were immersed into the name of the Lord Jesus. Then Paul placed his hands on them and [the supernatural power of] the Holy Spirit came on them and they [began to] speak in [other] languages and prophesy [i.e., speak God's message].

For we were all immersed by means of the one Holy Spirit into one body [i.e., the church], whether [we were] Jews or Greeks [i.e., Gentiles], whether slaves or free people, and were all given the one [and the same] Holy Spirit to drink. [Note: This probably refers to the indwelling of the Holy Spirit, given to all immersed believers. See John 7:37-39; Acts 2:38].
