Evangelical Dictionary of Theology, 2nd Edition
This is one of my most used resources. It covers a surprisingly wide range of topics, much more than many other dictionaries (e.g., "Aaron, Abaddon, Abomination, Abortion, Abraham's Bosom, etc.), including many theological topics. The articles are well-written by accomplished, evangelical scholars. After a good study Bible and concordance (and perhaps a word study book), this is the most important book to own.
The International Standard Bible Encyclopedia, 4 Vols
This is the standard, detailed encyclopedia for looking up almost anything you want in reference to the Bible and biblical topics. The articles are well written and complete. As opposed to some of the competition, the articles are also evangelical-friendly, which means that generally you can trust them. It is comforting to have a set of reference books that can help you, almost no matter what you are wondering about. The set is getting old, but I have not heard of any plans to update it.
