We have recently discovered a great resource for family devotions - Bible Bites. Written by Ladeane Lindsay and published by Anglican Youthworks, it was shortlisted for the 2011 Australian Christian Book of the Year.
It contains 356 (undated) family devotional times. Split into 7-day groupings, they are designed to be used daily, but could easily be used a few times a week instead. Each Bible Bite is based around a key biblical theme and memory verse. Over 7 days, you learn a memory verse together and look at difference aspects of that theme; which includes a bible reading, activity/sharing time and prayer. It is designed for children aged 3-12 and to take ~10 mins at a time. You could easily increase or reduce the suggested activity as family life and your energy dictates (I reduce it, having almost no energy for memory verse games!)
It covers 52 ‘Bites’ about God, his characteristics, key events in the bible, Jesus’ life, death & resurrection, and Christian living. Your family will end up with a fantastic grounding in the overall message of the bible and will have memorised lots of bible verses along the way.
We are 5 'Bites' in - having taken longer than 5 weeks to get there. I am pleased to discover that the kids remember all five memory verses still, and the salient points of the themes. All three (aged 9, 7, 5) are enjoying it and learning about God along the way.
A resource well worth using in the home.
