Why do we speak in tongues and have interpretation of tongues?
For if I pray in a tongue, my spirit prays, but my mind is unfruitful. So what shall I do? I will pray with my spirit, but I will also pray with my mind; I will sing with my spirit, but I will also sing with my mind (1 Corinthians 14:14,15).
Therefore, my brothers, be eager to prophesy, and do not forbid speaking in tongues (1 Corinthians 14:39).
If anyone speaks in a tongue, two — or at the most three — should speak, one at a time, and someone must interpret (1 Corinthians 14:27).
