Yes, tongues are one of several Spiritual gifts mentioned in 1 Corinthians 12:7-11, and Paul devotes 1 Corinthians 14 to more fully expounding upon its manifestation in the church. God the Holy Spirit has come to be our teacher, leader, and guide, so we are to learn to live, walk, and be led by Him. He began His teaching program by teaching us how to speak His language from which all divine utterances spring forth. Through tongues He introduced the unlimited dimensions of the power of God which has been given to us without measure (Acts 2:4, 1 Corinthians 12:10, 28, 14:21). There are many who may argue that it was not so in the Old Testament, which is true, but we are in a New Covenant with a far greater glory. As with all things spiritual, the language of the Spirit comes from the Holy Ghost – not from men. It is a divine utterance supplied by the Holy Spirit, not to be controlled by man. It serves to strengthen those who flow in it to function in other divine expressions and special supernatural abilities of God.
