Benjamin's Box (an Easter story)
Another option for doing Resurrection Eggs with your children... is to make them yourself. Here is a link to instructions on how to make your own. So this year instead of only taking your kids to an Easter Egg hunt for the candy... make some time to share the real meaning of Easter with "resurrection eggs". They suggest you start opening the eggs for 12 days before Easter.... but you can still do them now, and take fewer days to open them.
