Revised and Expanded. Lexicons and theological dictionaries often discuss a word without ever giving a succinct definition. In my years of writing, I have found that frustrating. So, in the course of writing commentaries and doctrinal works, I have had occasion to construct definitions for many words. The Bible doesn't define, but through careful observation of how a word is used, one may construct a useful definition. By combining lexicon, theological dictionary, and observation of use, I have defined many important biblical words in doctrinal and practical terms.
