1 Corinthians 14:6-9

J.B. Phillips New Testament

Unless “tongues” are interpreted do they help the Church?

⁶ For suppose I came to you, my brothers, speaking with “tongues!”, what good could I do unless I could give you some revelation of truth, some knowledge in spiritual things, some message from God, or some teaching about the Christian life?

^7-9 Even in the case of inanimate objects which are capable of making sound, such as a flute or harp, if their notes all sound alike, who can tell what tune is being played? Unless the bugle-note is clear who will be called to arms? So, in your case, unless you make intelligible sounds with your “tongue” how can anyone know what you are talking about? You might just as well be addressing an empty room!
