“It is clear that speaking in tongues is a sign of deep spirituality.” Is this statement true or false?

How about this one: “Speaking in tongues is necessarily a Christian phenomenon.”

 
The issue of tongues speaking is certainly controversial, and often generates more heat than light among brethren in the Lord. However, we should desire to understand God’s Word concerning this phenomenon, so BBN offers a very instructive course on the subject of tongues in its free online Bible Institute. Dr. Donald R. Hubbard tackles this issue head-on and gives straight and honest Bible answers to many questions that are often asked about this subject. Dr. Hubbard goes on to answer such important questions as whether tongues speaking is necessarily for every believer in Christ as well as whether a believer should seek for this gift. The course is numbered 50600 in the Electives Division of the Institute, and it is our sincere prayer that all who are seeking clear Bible answers to this often perplexing issue will study this course. Dr. Hubbard is fair and balanced and most of all Biblical in his exposition of this course. The student may not have all his questions answered but the most important ones will likely be answered according to the Word of God. May the Lord bless you as you study His Word on this and other crucial Biblical issues.
