We have a very large number of audio Bible-studies that you can download freely. The older ones would be about 30 minutes or longer, whereas the more recent ones are less than 5 minutes long. The briefer ones will be a great help to those who wish to study the Bible in spite of their busy schedule. These brief studies are well-suited for mobile devices where you can listen to the studies while on the move.
