Biblos.com presents a fairly common interface to the internet, which should be of reasonable comfort to members unfamiliar with the program. The menu bars it uses, and the 12 English Bibles it encompasses, will certainly provide the basics needed for people to move beyond bare bones Bible study. A nice feature if you have a multilingual congregation is the inclusion of many foreign language Bibles, including multiple choices in a number of these languages.
I especially enjoyed finding the online mobile version (Online Mobile Bible), for which it claims the only requirement is Internet access. A quick try proved it works with my Samsung Blackjack 2, and the features extend beyond a simple electronic copy of the Bible (in the 12 English variants); it also has 3 commentaries and cross reference features. It works with PDA’s and computers, so you could use this on a computer’s larger screen if you’re having difficulty reading the phone’s screen.
There is a wealth of ways to interpret and/or approach a Bible text using the Bible study Tools option. While not extensive, it provides 25 different methods to get into the text and expand your knowledge, from parallel gospels to interwoven text (Hebrew or Greek). It has a feature for searching on a story, date, person, place, or topic, so it you are one who doesn’t like to memorize the minutiae, you could easily use this feature to take you from the general to the specific.
