"Be still and know that I am God..." Psalms 46:10
Everyday we should have some sort of down time to refocus, relax and recommit. Even secular society realizes we need a break (thus why most have weekends off). Having a quieter time during the morning, day and/or night is what God is asking, in fact He commands it.We don't have to be "doing" anything, except being.
Meditating on a Scripture and God, think about Him and what He is all about...being quiet and being in awe. Don't say anything, don't do anything. When your mind wonders ask for it to be drawn back to Him.
If you are one that can't be still, then how about Christian Yoga? Put in a worship CD and be still, breathe slowly, meditate on God and stretch your body. A song I love is by Fernando Ortega, "Give Me Jesus" - a download must!
When was the last time you were still before God?
