He asked them, “Did [any of] you receive the [indwelling] Holy Spirit when you became believers [in Jesus]?” They answered him, “No, we have never [even] heard that there was a Holy Spirit.”
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].
For I know that, through your requests [in prayer] for me and the help provided by the Holy Spirit of Jesus Christ, this situation will result in my being rescued [i.e., released from imprisonment].
