Even though I am not schooled in Greek, Hebrew, or Latin, the book is still understandable to a lay person. Walter Martin has researched the Scriptures well and given many Bible verses to look up to back up his claims. Understanding how these cults twist the Word of God is helpful in refuting their claims.
The latest version of a great classic on the subject. Concise and to the point...enough for the discerning apologist or evangelist to grasp a good understanding of what the cults teach, how they ensnare and manipulate, and the lies they perpetuate. A good and interesting read for any Christian.
