He explains how this infilling is a separate work that takes place after salvation. He confirms in scripture, as he moves through the Book of Acts, how Tongues is the evidence that a believer has been filled with the Holy Spirit. Brother Donnie explains how tongues is not a requirement to get into heaven, but how this gift from God can help a believer in his daily walk and produce a life of service for the Lord.
