1 Corinthians 14:20-22

New Revised Standard Version Updated Edition

²⁰Brothers and sisters, do not be children in your thinking; rather, be infants in evil, but in thinking be adults.^(A) ²¹In the law it is written,

“By people of strange tongues
and by the lips of foreigners
I will speak to this people,
yet even then they will not listen to me,”

says the Lord.^(B) ²²Tongues, then, are a sign not for believers but for unbelievers, while prophecy is not for unbelievers but for believers.
