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

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

{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.

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.
