This is such a broad topic! The first thing that comes to mind is simplifying my home. Less stuff to be exact. Less clutter. Being a good steward of money. Making use of what we can. Minimizing waste. Yes, it borders on the movement of "Being Green". I believe it is important to be mindful of all the things I've listed.
But before all of these things I have learned that "living simple" can, if I choose, afford me the opportunity and privilege to lead a more Christ centered life. I am guilty of always rushing around, especially rushing my kids. That is not simple. I have been working really hard to minimize distractions or in my eyes "living simply" so that I can praise God, pray, study the Bible, and share these things with my family. I have had to remind myself that: my children do not have to be involved in a sport each season, it is OK to make a mess... a big mess to do a craft with my daughter, I should sit to nurse instead of trying to multitask and wash dishes while doing so, it's OK to take a nap, the laundry can wait- as long as we have clean underwear :) , and the list can go on. Letting go of these things or better yet succumbing to some of them has helped me to have a clearer mind. So for me "living simple" means not over commiting, learning to say no, and consuming and buying less therefore I have less to take care of. It takes effort!
What does it mean to you to "live simple"?
