They say you don't know something until you can explain it to a child. Have you ever tried to summarize the Bible for a preschooler?
It's some three times longer than Moby Dick, 35% longer than Tolkien's The Lord of the Rings, and about 24,000 more words than War and Peace. No wonder it's difficult to accurately relate the story of Scripture to your preschooler!
Christians have taken different approaches over the years to teaching the Bible to children. It's hard to improve upon catechisms as a way to teach doctrine. They also help children engage mentally with the truths of Scripture. They don't however, always help children understand the story line of Scripture.
More often than not as of late, Christians have resorted to just rehearsing individual biblical stories. While this approach does help kids engage with the events of Scripture, it doesn't really portray a full-orbed understanding of the Bible. It also very quickly leads to mere moralism.
So how do you teach the Bible to a preschooler? First, don't despair! You're not alone. Second, pick up one of these great resources. You can continue to rehearse biblical stories and definitely continue to catechize your children. But these resources will help provide a basic framework, a basic story arc to your children so they will be able to position the truths they learn within God's overall plan.1
