There's a fun and snappy 4 minute video on a site called max7.org which can be used as a tool to inspire leaders, churches and ministries with the story of what God is doing across the world, specifically in relation to children. I can't download the video to this blog (at least as far as I can figure out) so you'll need to go to the site to watch it or download it yourself.
You could use it as part of a training presentation, in your church or at a missions conference. Though it's simply done, it's designed to think about the big picture of children in the Bible and across the world, without shying away from the challenges that children are facing.
Max7 resources have been freely donated for people's use so the video can be used widely (as long as it's not sold).
