The iFaith project takes us through the entire Bible. From each book of the Bible are produced 1 or 2 video sermons. All talks are 15 minutes or shorter, and are suitable for viewing followed by discussion. Yet they may also make a good introduction to the Bible as a whole. Click on the link above to see the entire plan.
The second series is on the Sermon on the Mount. For these 26 videos, click here (and scroll down).
