'Uninformed' in the Bible

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

Otherwise, if you praise with the spirit, how will the uninformed person say “Amen” at your giving of thanks, since he does not know what you are saying?

Therefore, if the whole church assembles together and all are speaking in other languages and people who are uninformed or unbelievers come in, will they not say that you are out of your minds?

But if all are prophesying and some unbeliever or uninformed person comes in, he is convicted by all and is judged by all.
