Take a look at the Bible Society's online introduction to Mark’s Gospel - it is a fresh and engaging series of short videos that lead us through the awesome Jesus story...with Australian accents all the way!! This would be a fantastic resource to watch with children. Download the workbook(very clear and easy to use) and take some time to learn about the earliest Gospel. This particular bible reading takes a few minutes a day for 16 days or episodes. See what you think.
