"For who has known the mind of the Lord; who has advised him?" But we have the mind of Christ.

{Therefore what should I do}? I will pray with my spirit, but I will also pray with my mind. I will sing praise with my spirit, but I will also sing praise with my mind.

Now I exhort you, brothers, by the name of our Lord Jesus Christ, that you all say the same [thing] and there not be divisions among you, and that you be made complete in the same mind and with the same purpose.

For if I pray in a tongue, my spirit prays but my mind is unproductive.

but in the church I prefer to speak five words with my mind, in order that I may instruct other [people], than ten thousand words in a tongue.

Therefore, if the whole church comes together at the same [time] and all speak with tongues, and outsiders or unbelievers enter, will they not say that you are out of your minds?
