1 Corinthians 14:10-12

Amplified Bible, Classic Edition

¹⁰ There are, I suppose, all these many [to us unknown] tongues in the world [somewhere], and none is destitute of [its own power of] expression and meaning.

¹¹ But if I do not know the force and significance of the speech (language), I shall seem to be a foreigner to the one who speaks [to me], and the speaker who addresses [me] will seem a foreigner to me.

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.
