BibleProject is a Portland-based nonprofit that creates animated videos explaining the Bible's literary structure, key themes, and narrative unity. Every video is free — BibleProject's stated mission is to make biblical education available to anyone in the world at no cost, funded entirely by donors.
The quality is exceptional: the animations are beautiful, the theology is careful, and the explanations are genuinely illuminating without being dumbed down. For an SRE teacher, using a BibleProject video at the start of a lesson unit does in 7 minutes what might take you 20 minutes of introduction to explain yourself — and it does it with visuals that make abstract concepts stick.
