Bible Verse

For anyone who speaks in a tongue does not speak to people but to God. Indeed, no one understands them; they utter mysteries by the Spirit.

1 Corinthians 14:2

For this reason the one who speaks in a tongue should pray that they may interpret what they say.

1 Corinthians 14:13

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

1 Corinthians 14:14

So what shall I do? I will pray with my spirit, but I will also pray with my understanding; I will sing with my spirit, but I will also sing with my understanding.
