Even those believers who profess theological belief in the modern-day occurrence of tongues do not necessarily speak in tongues so regularly. This sermon offers a powerful biblical and Pentecostal defence of tongues and shows why praying in tongues is so beneficial. Highlighting the difference between the public use of the spiritual gift of tongues and the personal use of tongues as a prayer language, the sermon looks at Paul’s teaching in 1 Corinthians and deals with some of the common misunderstandings.
