1 Corinthians 14:20-22

JMNT(i) 20 Brothers (= Fellow members of the community)! Stop becoming little boys and girls in or by [your] way of thinking and use of intellect, but still be infants – non-speaking babies! – in the worthless, the ugly and the poor of quality or the evil. Yet progressively come to be mature as folks which manifest the purpose (full-grown; perfect; ones having reached the goal and express the destiny; or: = adults) in [your] way of thinking and use of intellect. 21 It has been written within the Law that, "In different (= foreign) languages (tongues) and with different (= foreign) lips shall I proceed in speaking to (with; in) this peopleand not even in this manner will they proceed in paying attention to Me, or listen into and obey Me," [the] Lord [= Yahweh] is saying. [Isa. 28:11] 22 Consequently the languages (tongues) are [pointing] unto and [leading] into a sign – not for believers (or: to those constantly trusting), but rather for unbelievers (or: to those without trust or faith) – yet the prophecy (the publicly spoken message [from God]; the speaking of light ahead of time) [is] not for (or: to) unbelievers, but rather for believers (or: to those habitually trusting, progressively believing with conviction, and continuing loyal).
