1 Corinthians 14:12-14

Amplified Bible, Classic Edition

¹² So it is with yourselves; since you are so eager and ambitious to possess spiritual endowments and manifestations of the [Holy] Spirit, [concentrate on] striving to excel and to abound [in them] in ways that will build up the church.

¹³ Therefore, the person who speaks in an [unknown] tongue should pray [for the power] to interpret and explain what he says.

¹⁴ For if I pray in an [unknown] tongue, my spirit [by the ^[a]Holy Spirit within me] prays, but my mind is unproductive [it bears no fruit and helps nobody].
