So I own the Lexham Theological Wordbook. Similar terms are grouped together in the Lexham Theological Wordbook. That is, while researching a subject or concept, you can consult the Wordbook for synonyms. It appeals to me because it explains words rather than merely defines them. I have been seeing The Theological Wordbook General Editor: Charles Swindoll being used in more academic studies. What is the difference between the two resources?
