1 Corinthians 14:20-40

Continuing the comparison of tongues versus prophecy, Paul turns to how each is viewed by unbelievers. The unbeliever may be convicted by prophesy that he can understand and turned off by speaking in tongues, thinking the person is crazy. Paul counseled for an orderly worship service where the speaking of tongues was limited and always accompanied by an interpretation.

People think Christians talk strangely enough already. Why compound it with something that would sound completely crazy to someone who doesn't know what's going on? At all times, when we talk about our faith, we should do so in a clear and easy to understand way so that everyone can understand what we say and benefit from it. Our worship services should not be an insiders' club where only members can understand what's going on. If we are to reach out to our community, we must make sure they feel welcome and are able to follow what is being said.
