1 Corinthians 14:14-15

Amplified Bible

¹⁴ For if I pray in a tongue, my spirit prays, but my mind is unproductive [because it does not understand what my spirit is praying]. ¹⁵ Then what am I to do? I will pray with the ^[a]spirit [by the Holy Spirit that is within me] and I will pray with the mind [using words I understand]; I will sing with the spirit [by the Holy Spirit that is within me] and I will sing with the mind [using words I understand].
