'Uninformed' in the Bible

With regard to spiritual gifts, brothers and sisters, I do not want you to be uninformed.

So if the whole church comes together and all speak in tongues, and unbelievers or uninformed people enter, will they not say that you have lost your minds?

But if all prophesy, and an unbeliever or uninformed person enters, he will be convicted by all, he will be called to account by all.
