When my teens were little, this kind of Advent Calendar could easily be found. We used to purchase one every year and our then little ones would have the Christmas story in scripture memorized by Christmas day.
When our little ones came along, we had a harder time finding the calendars I wanted. I didn't want there to be a picture of a star or SpongeBob or even Veggie Tales characters - I wanted there to be scripture verses. Some years I skipped the Advent Calendar altogether when I couldn't find them.
I look every year and this year I hit the jackpot! Berean Bookstore carries this sweet, old fashioned Advent Calendar! A bonus was that they were the least expensive ones they sell! I bought 3 this year. One for our nieces Sara Anne and Anna and one for our great nephew Elijah, and one for my children! I intend to save ours every year now just in case I can't find them next year. I may go out and get one for my new great nephew, who is still being knit together in his Momma's womb, sweet Alicia's little wee baby.
I want a legacy left for my children and the children of my nieces, nephews, and one day my own grand children. I want that legacy to be a Christ Centered Christmas, and life. I pray that each precious one comes to know the Saviour, Jesus. The true reason for the season!
