I remember as a child of maybe 10 or so, filling a shoebox with Christmas gifts for a child in war-torn Bosnia, to be delivered by an organization called Samaritan's Purse through an effort they called "Operation Christmas Child". My three siblings and I each carefully selected toys, crayons, mittens, and scarves, wrapped our shoebox tops and bottoms separately, and then each wrote a letter to the child we were sending the gifts to. My child wrote back to me, and I corresponded with this girl for the next couple years.
During my first year at college in Santa Barbara, I was again given the opportunity to fill shoeboxes with Christmas goodies, and I took great joy in filling two shoeboxes, one for a little girl and one for a little boy, to be shipped I don't know where this time.
This year, the Lockwood family, a missionary family in Mexico that I follow by blog, will be passing out Christmas shoeboxes to the children in the town where they serve. They are hoping to be able to pass out ~200 boxes, bringing joy to each child and an opportunity to share the source of true joy, Jesus Christ. I have already made a couple of boxes to send, and have had so much fun doing it! Here is a link to the instructions they have posted if anyone is interested in making one!
