In the case of ' Tongues ' it is the Mind of the Holy Spirit that Gives the utterance.   

You do not typically start moving your Tongue until You have a thought.   This is your Mind controlling the Tongue.   

In the case of ' Tongues ' You must Give the Holy Spirit the Authority to Give utterance to His Thoughts.   This is Why it is difficult for some people to Manifest ' Tongues '.   They Will not Give control to the Holy Spirit.

• 5 Questions regarding tongues
  1. Is Speaking in Tongues required?   
     No.    1 Corinthians 12:30 - Have All the Gifts of Healing ?   do All Speak with tongues?   do All interpret?   
     

  2. Why Speak in tongues?   
     It edifies the believer.   
     1. The Manifestation that came with the Gift of the Holy Spirit was Speaking in tongues.   It wasn't the wind, Fire , noise or feeling of God's Presence that was evidence of the Gift being Received but a Spirit language Believers began Speaking languages of the Spirit they didn't Understand.   It was God's plan for the Gift to function as a Spirit language for His Children ( (Acts 2:4, 11; 1 Cor.   14:2 ).   

     2. The Scriptures Exhort us to be filled with the Spirit and to Pray in the New Tongues of our Spirit language.   Our Spirit language Enables us to Live in the Spirit , Walk in the Spirit , be led of the Spirit , have the Fruit of the Spirit , Manifest the Gifts of the Spirit and go from Glory to Glory until we are Transformed into His same Image ( (Gal.   5:22-25 Rom.   8:14 1 Cor.   12:7-11 14:15 Eph.   5:18 Acts 19:2 2 Cor.   3:18 ).   

     3. A Spirit language is the greatest Gift the Holy Spirit can Give a Believer.   Jesus is the greatest Gift God could Give for the Redemption of the world, and the Holy Spirit is the greatest Gift Jesus could Give to His Church.   Of All the resources in Heaven and the Eternal Universe , nothing is more valuable, beneficial or important for the Holy Spirit to Give the individual Child of God than her own Spirit language ( 1 Cor.   12:31 1 Cor 14:4 ).   

     4. Our Spirit language Enables us to have spirit-to-Spirit communication with God.   Humans are Spirit beings clothed with flesh-and-bone bodies.   While man's Sin deadened the Spirit , Jesus brings the Spirit back to Life by imparting His everlasting Life into us.   The Holy Spirit Gives us a Spirit language so we can communicate directly with God ( (John 4:24 1 Cor.   15:45 Gen.   2:7 Rom.   5:12 John 3:3-5,16 ).   

     5. Praying in Tongues builds and Increases our Faith.   Faith is the medium of exchange for All Heavenly things, Just as Money is the medium of exchange for All earthly things.   A major Way to Increase our Faith is to Pray in the Tongues of our Spirit language ( (Rom.   12:6 Jude 1:20 Mark 9:23 Matt.   9:29 ).   

     6. Praying in our Spirit language is the main Way we fulfill the scriptural admonition to "pray without ceasing." Christians can Pray in Tongues at any Time.   If we are in a Place where it isn't convenient or wise to Speak out loud in tongues, we can Pray with our inner man without making an audible sound ( (Eph.   6:18 1 Thess.   5:17 Matt.   26:41 Luke 18:1 21:36 1 Cor.   14:15 ).   

     7. The Holy Spirit directs our Spirit language to Pray in accordance with the Will of God.   Probably the Only Time we can be assured that we are Praying 100 percent in the Will of God is when we are Praying in our Spirit language.   God always answers requests that are made in alignment with His Will ( (Rom.   8:27 1 John 5:14-15 ).   

  3. Why is it divisive?   
     Satan.   He is the author of Confusion.   Confusion is the opposite of accord.   Most of the divisiveness in Christianity is a result of Pride while the Rest may be contributed to Ignorance.   It is Human Nature to Believe 'I am right'.   It is Human Nature to Believe 'I am special'.   Satan plays upon these basic Human characteristics to undermine the wonderful Nature of Grace and Word and Spirit.   

  4. Can a Spirit filled person Speak in Tongues at will?   
     Yes.   The Corinthian Christians were out of Order in their Services because they chose to Speak in Tongues rather than Hear the Word and Minister to the unsaved.   It is the Spirit that Gives the utterance.   So, it is necessary that the Believer be in the Spirit - i.e.   be focused on and yielded to the Spirit.   If a person Speaks in Tongues and they are not in the Spirit is mere babble.   There is no Edification in babble.   

  5. How do You Speak with tongues?   
     Believe in it.   Understand it.   Desire it.   Ask for it.   Become absorbed in the Majesty , loveliness and person of Christ.   Yield your Tongue to the Holy Spirit.   See Spirit Baptism.
