I’m a relatively new convert to Protestantism (2 years). Having been raised Catholic, I feel I do not have the solid understanding of the Bible that I should. I’m also a geek. So naturally, I have bible study software on my computer. Here’s a brief overview of the applications I’ve tinkered with, and which I recommend.
JSword Bible Desktop
http://www.crosswire.org/jsword/
JSword is a powerful free application that makes Bible study easy. It features parallel bible comparisons, footnotes, dictionaries, devotional readings, and is fully expandable through JSword bible and resource modules. It is available for free under the GNU General Public License.
This is the application I’m currently using, and I’m fairly happy with it. It still has some minor bugs that need to be worked out, but I’m confident that this will eventually parallel e-Sword in features and performance. I highly recommend using this.
E-Sword
http://www.e-sword.net/
E-Sword is a free, closed-source application and probably one of the best applications out there. It has virtually all the features of JSword projects, but is much more refined and stable. It also provides Bible modules containing the Deuterocanonical and Apocryphal books, Strongs concordance, and other nice features one would hope to find in a commercial Bible study application.
The only downside is that it is not open source, and it is restricted to the Microsoft Windows platform. It also lacks the easy module manager of Bible Desktop. Nonetheless, if you use Windows, I highly recommend trying this out.
MacSword
http://www.macsword.com/
This is another free, open-source Sword-based project. It features a very nice Aqua user interface. It is relatively easy to use, but lacks a lot of the more powerful features of Bible Desktop. If you are a Mac user, I recommend checking both Bible Desktop and MacSword to see which you like better. It’s not my favorite application, but it’s worth looking at.
As much as I like to support free and open-source software, one drawback is that many modern bible translations are restricted by copyright and cannot be used in these applications. Given that, I may cave-in and pay for a commercial application. But for now I’m happy with Bible Desktop, and using the hard copies of more modern translations when necessary.
