This book was made available in 1971, and is my favorite one that addresses what the scriptures have to say in the New Testament about this spiritual gift of speaking in tongues. Merrill Unger is an incredible Theologian that has communicated clearly concerning the texts that are sited, explaining the purpose, regulation, Church History, and Evaluation of Tongues Today. It is as relevant today, as it was in 1971. If you are as confused about this subject as I was, you will be pleased to grasp the New Testament teaching on a significant gift.
This is a wonderful book that gives a sound, Biblical teaching on the Holy Spirit. I am an ex-Charismatic and I wish I had read this before I was ensnared in the modern Charismatic deception. If you want solid Scriptural teaching on the Holy Spirit, this book offers it. Unger addresses all the Scriptures that Pentecostals and Charismatics conveniently over look as well as the ones they take out of context to try to prove their point. This book gives sound Biblical teaching in this day of apostasy.
Merrill Unger failed to give the scriptural account of when Jesus Christ, the Christian example, received the holy ghost himself. The spirit descended upon him like a dove, and spoke "This is my beloved son in whom I am well-pleased." We do not serve a deaf-mute God. He even forgot to note Isaiah, with stammering lips and another tongue will he speak to his people.
