I bought this almost 20 years ago. Advent calendars (this one has ornaments that have the names of God with correlating information on His names) are a simple yet powerful way to keep Christ in Christmas. The ornaments are durable and each day we read the name of God and its history before placing the ornament on the tree.
One thing, though! When I looked this up online it came up on Amazon. It's out of print and ... sells for $200 and $100!
So, you may not want to purchase this particular one but look for it at yard sales. It's a keeper for the content ... but it's also valuable!
