Okay, this isn't a Bible study program, but it is a free download of the Open Office Suite of software comparable in quality to programs you'd pay a great deal for otherwise. The suite includes all the major programs a typical office might use, specifically Writer, Calc, Impress, Draw, Base, and Math. Compatible with other major office program suites, without spending hundreds of dollars, and every bit as good.
