1 Corinthians 14:14-16

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]. ¹⁶ Otherwise if you bless [and give thanks to God] in the spirit only, how will any outsider or someone who is not gifted [in spiritual matters] say the “Amen” [of agreement] to your thanksgiving, since he does not know what you are saying?^(A)
