Couldn't help thinking that its really no accident you are so busy and your life is so interrupted because that is the real place to learn and practice simplicity Yes, we need to get rid of things God has not called us to do, but real people have interruptions. The secret is a singleness (simplicity in a way) of mind and heart in the whirlwind.
Then as I reread the familiar scripture of Martha and Mary in Luke chapter 10, one thought jumped off the page. One thing is needful! Maybe the analogy was to reinforce to Martha that one simple dish for the Lord would have sufficed instead of her trying to "serve" Him in an elaborate manner. (She must have lived in "the South" of Bethany, to have such a southern mentality.) But I think He was commending Mary as well for focusing on one thing as she sat at His feet.
But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her. (Luke 10:42, KJV)Underlining brings that snippet into focus for me---with singleness of mind and heart, I narrow my concentration to focus on the one thing that is needful. Time at His feet. That's simple enough.
