I own several other Bible dictionaries (e.g. New Bible Dictionary, Nelson's Illustrated Bible Dictionary, Eerdmans Bible Dictionary) and I use this one the most. This edition is revised and updated by the editors R.K. Harrison, Howard F. Vos, and Cyril J. Barber (all renown evangelical scholars). It is much better than the older Ungers Bible Dictionary.
Dr. Merrill Unger is an evangelical scholar who holds to the full inerrancy of Scripture and who adopts a conservative viewpoint regarding the authorship of books such as Isaiah and Daniel. He believes in the single authorship of Isaiah and holds to an earlier dating of the book of Daniel. His views on the prophetic / apocalyptic books such as Daniel and Revelation reflect a premillennial dispensationalist viewpoint (i.e. futurist view); that is, he believes that Israel and the church are distinct from one another and have distinct purposes, the Rapture will come before the Great Tribulation, the millennium is a literal 1,000 years, etc. Regarding the rite of baptism, Unger is careful to explain both the Baptist and non-Baptist views. Concerning the Lord's Supper, he does a brief treatment of the different views regarding the essential nature of the elements in the Lord's Supper.
The entries are very clearly written and easy to understand. Interspersed throughout are helpful maps, colored illustrations, and black and white photographs.
If you want a clearly written Bible dictionary written from a conservative, evangelical viewpoint, this dictionary is for you.
I turn to this reference first when I'm in need of a quick, comprehensive treatment of a topic in the Bible. It's my favorite Bible dictionary. It explains everything clearly, succinctly, yet comprehensively. Highly recommended!
