I have been a long time user of e-Sword (alongside BibleWorks) and cannot recommend it highly enough. It is a free Bible study software program that rivals many that you would have to pay for and is better than most. This program also makes basic word studies a breeze and has been of great use to those in my congregation to whom I have recommended it.

There is not a very steep learning curve with this program, so most anyone can catch on to it fairly quickly. The most recent update was made on August 25th and “includes the latest versions of third-party components used within e-Sword,” as well as “many little enhancements and bug fixes.” For those interested, here is a history of updates going back to version 5.
