1 Corinthians 14:15

15 What should I do then? I will pray with the spirit, but I will pray with the mind also; I will sing praise with the spirit, but I will sing praise with the mind also.

1 Corinthians 14:15 In-Context

13 Therefore, one who speaks in a tongue should pray for the power to interpret.
14 For if I pray in a tongue, my spirit prays but my mind is unproductive.
15 What should I do then? I will pray with the spirit, but I will pray with the mind also; I will sing praise with the spirit, but I will sing praise with the mind also.
16 Otherwise, if you say a blessing with the spirit, how can anyone in the position of an outsider say the "Amen" to your thanksgiving, since the outsider does not know what you are saying?
17 For you may give thanks well enough, but the other person is not built up.
