Being baptized in the name of Jesus enables the Holy Spirit, who answers to the name of Jesus, to fill you. If you weren't baptized in the name of Jesus, you need to be baptized again just as Paul did to the 12 Ephesians in Acts 19 who believed but never knew the Holy Spirit. Paul had to baptise them again in the name of Jesus and the Holy Spirit filled them to the extent that they spoke in tongues and began to prophesy.
