1 Corinthians 14:14,15,18

¹⁴For if I pray in another language, my spirit prays, but my understanding is unfruitful. ¹⁵What is it then? I will pray with the spirit, and I will pray with the understanding also. I will sing with the spirit, and I will sing with the understanding also. ¹⁸I thank my God, I speak with other languages more than you all. 1 Corinthians 14:14,15,18
