Two of the newest Bible websites that are worth mentioning—mystudybible.com and lumina.bible.org will be gaining more visitors and users as the good news spreads. Plus, there are certainly many other Bible websites with Bible software, apps, content, study materials, videos, media, and so on; though the list here is primarily focused on just the Bible, plain and simple.
