^20 (A)Brothers, ^(B)do not be children in your thinking; rather in evil ^(C)be infants, but in your thinking be mature. ²¹ In ^(D)the Law it is written, “^(E)By men of strange tongues and by the lips of strangers I will speak to this people, and even so they will not listen to Me,” says the ^[a]Lord. ²² So then tongues are for a sign, not to those who believe but to unbelievers; but ^(F)prophecy is for a sign not to unbelievers but to those who believe.
