This book is a comprehensive biblical study that exposes the growing confusion surrounding the modern practice of “speaking in tongues.” While many believers today assume that every spiritual experience labeled as “tongues” comes from the Holy Spirit, the Bible presents a very different and much clearer picture. This book aims to bridge the gap between what Scripture truly teaches and what modern teachings have added through tradition, emotion, and misunderstanding. Beginning with the historical events of Babel and Pentecost, the book carefully examines the origin, purpose, and function of languages in the Bible. It reveals how the first biblical gift of tongues was not an unintelligible sound, but real human languages given for the expansion of the Gospel. Through detailed commentary, scriptural analysis, and practical insights, the book contrasts biblical truth with today’s practices, exposing areas where the church has drifted away from sound doctrine. The purpose of this book is not to criticize any group, but to guide believers into spiritual discernment. It answers critical questions: Is every modern tongue from the Holy Spirit? Should every believer speak in tongues? What does Paul actually teach about order, purpose, and interpretation? And how can the church avoid deception? This book is essential for anyone who desires to understand the biblical truth about spiritual gifts, differentiate between genuine and counterfeit experiences, and return to the clarity and purity of God’s Word.
