“What 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.”
King James Version (KJV)
14:15 I will pray with the spirit, but I will pray with the understanding also - I will use my own understanding, as well as the power of the Spirit. I will not act so absurdly, as to utter in a congregation what can edify none but myself.
1Co 14:15 What is it then? How then am I to act? He answers that question. I will pray with the spirit and I will pray with the understanding also. He will have both the spirit and the understanding unite in singing and praying, by using a tongue that he understands.
