"Everything is lawful," but not everything is beneficial. "Everything is lawful," but not everything builds others up.

But now, brothers, if I come to you speaking in languages [supernaturally], how will I benefit you unless my speaking consists of a revelation [from God], or a [message of] knowledge [See 12:8], or a prophecy, or a teaching? [i.e., the message must be intelligible to be beneficial].
