The kids and I have been enjoying listening to an online radio series called, "Adventures in Odyssey" during our lunch time. This is a radio series produced by Focus on the Family and has been around since I was a child. The production is not archaic, though. It's fresh, lively, and touches upoon topics relevant to growing up with Christian values in a broken, Christ-needy world. I would highly recommend listening to this radio series with your children as it often provides a context to talk about God's truths, principles and how to apply them to everyday life situations.
Below is a link (copy and paste) to listen to one of our most recent favorites. We've listened to it 3 times in the span of several days. :)
