I have been participating in this challenge for 10 days now, and I love it! The devotions have really "hit me where I live" and the daily Martha tasks are not as overwhelming as I feared they would be (though we have yet to get to cleaning out closets which is my big trouble area). My kitchen is looking fantastic at this point, and though my husband was very amused and condescending about using a book to help me get organized, he loves the results.
The best part about the challenge is it has made me realize the importance of what I am doing each day. I very easily fall into the trap of thinking what I do is so incredibly temporal (sometimes lasting for mere seconds, as in the case of my clean kitchen floor) and fail to see the eternal value to my efforts. It has also made me focus on what I want from my home- a place of respite, beauty, and peace. When I view it with that big picture mentality, it makes scrubbing a toilet feel a lot more worthwhile.
