1 Corinthians 14:20-22

New International Version - UK

²⁰Brothers and sisters, stop thinking like children. In regard to evil be infants, but in your thinking be adults. ²¹In the Law it is written:

‘With other tongues
and through the lips of foreigners
I will speak to this people,
but even then they will not listen to me,
says the Lord.’^[a]

²²Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is not for unbelievers but for believers.
