I know I'm a broken record, but I highly recommend that if you want to add something, add honoring the Lord's Day. Most people are absolutely convinced that they are far too busy to do such a thing, but it is actually a commandment. Seriously, do you think God would give you a commandment that would make your life worse? Typically, keeping Sunday holy would include things like not doing heavy physical work on Sunday, going to church, spending time with family and friends, relaxing, avoiding shopping or errands (remember that if you shop someone else is unable to honor Sunday because they have to be there for you). Because you can't run yourself crazy doing all those things, you may have a little more time to do some extra reading or devotions.
I love my Sundays. It adds balance to my whole week, and I am so much more organized and able to get things done. While it is a day set apart for Him, it is a day that I need. I go to church, I usually try to call my family, if I do physical activity, it's usually an easy walk rather than something difficult, it's a good day to hang out with friends. It is a day we need. After all, man was not made for the sabbath, but the sabbath was made for man.
How is everyone else getting ready for Lent?
