On Speaking in Tongues

The Greek word γλώσσα (glóssa) means tongue or language. A Tongue may refer to the physical organ (Mk 7:33, 1 Cor 14:9, James 1:26). It may also mean ‘the language used by a particular people in distinction from that of other nations.’[1] This is how it applies to Acts 2:11; Isa. 66:18; Dan. 3:4, 5:19. When used this way, it refers to a common language people speak, like English or Luganda or Chinese, or a language that is unintelligible to man.
