I thought that this was a great idea and would be a great tool for the kids to learn to use early in life. This would help them (and me) to get use to leaning on God for their concerns and thanking Him for their blessings.
I talked to the kids about it, and I asked them what kind of prayers would they like to send to God. I love their answers, kids are so in tuned to what is going on around us.
I also thought it would be great to hold on to these prayers to look back and see what problems layed heavy on our hearts and how they are answered. Sometimes, "Some of God's greatest gifts are unanswered prayers."
I bought my box at "Michael's" ( a Craft Store) and stained it. There are so many many ways to do this and Michael's has so many different kind of boxes. Another idea I was thinking of was to have each child decorate their own box. The possibilities are endless.
It would make for a great gift for the kids to make and give to someone for Christmas.
