In 1 Corinthians 14, Paul gives instructions for the use of tongues in public worship. It profits on one, Paul says, for someone to blather on in a tongue if nobody understands it. The tongues-speaker is welcome to speak to himself and to God in private, but in public worship, Paul says, tongues must be interpreted.
Makes sense, right? Seems simple enough.
Here’s the problem, though: how do you know if there’s an interpretation?
Think it through like a scene in a movie. Someone feels moved by the Spirit to stand up and speak in a tongue, but he’s not supposed to do it unless someone can interpret it. Does he have to find an interpreter in advance? How does that work? (“Hey, buddy — I’m gonna speak in tongues. Do you have the interpretation?”) Does he just speak, and trust that the Spirit will give someone the interpretation? How long do we let him go on before we decide there’s no interpreter, and have him sit down?
See, Paul sets them up for a “try it and see” model here. To even have a hope of following Paul’s instructions, they’ll have to rely on the Spirit, and discern His will together.
And so should we all.
