Let me explain this.
My date book stays closed.
I do not plan anything, look ahead into my week, or worry about the week to come.
Instead, I focus on what the day means: a resting of the body, mind, and soul.
By resting my Body, I do no unnecessary work. (No catch up, no laundry, no cleaning, no organizing.) I will cook and clean up meal preparations.
By resting my Mind, I will not plan out my coming week, or indulge any worries or concerns. It is a discipline to focus on this day as being one free of worries, or concerns, and mainly rest.
By resting my Soul, I read and meditate Scripture, and listen to worship music, as well as attend church service, where I am fed spiritually for the coming week.
Now, you might say...
"Shouldn't every day be a day of mental rest? Isn't that why Jesus came?"
And I would say, "Yes."
Jesus did say:"Come to me, all you who are weary and burdened, and I will give you rest. Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. For my yoke is easy and my burden is light." (Matthew 11: 28-30 NIV)
Every day should be a day of mental and emotional rest for our souls. This is why Jesus came, and reconciled the law. The Christian life is a continual Sabbath.
But what I find, on the Sabbath, is that a break from the necessities of life: the planning, the doing, that is a necessary part of life really forces me to have the emotional and mental rest on the Sabbath, just as doing no uneccesary work on the Sabbath gives my body the rest it needs.
