(1Co 12:10) “To another the working of miracles; to another prophecy; to another discerning of spirits; to another divers kinds of tongues; to another the interpretation of tongues:” The Book of Acts Chapter Two reveals tongues are known languages. They were given for the purpose of speaking to the Jew. The Jew was to recognize God’s Word as being fulfilled. Yet God knew they would not obey it: (1Co_14:21) “In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord. (22) Wherefore tongues are for a sign, not to them that believe, but to them that believe not:” So, in reality it was for condemnation of rejecting His Word – His Son.
