1 Corinthians 14:19 In-Context

17 For you may give thanks well enough, but the other person is not built up.
18 I thank God that I speak in tongues more than all of you;
19 nevertheless, in church I would rather speak five words with my mind, in order to instruct others also, than ten thousand words in a tongue.
20 Brothers and sisters, do not be children in your thinking; rather, be infants in evil, but in thinking be adults.
21 In the law it is written, "By people of strange tongues and by the lips of foreigners I will speak to this people; yet even then they will not listen to me," says the Lord.
