How important is rest to the human body? Important enough that God would model it after the sixth day of creation. Do you think He was actually tired after creating the whole world and everything in it with His “Word” and His “Spirit”? Rest is essential but not always easy to achieve. You may lie down to rest but your brain is hard at work. Until you put your mind at peace, rest cannot complete its work.
What’s the purpose of rest? To rejuvenate, recover and re-fuel. If we don’t get proper rest what are the consequences? Emotional and/or Physical Breakdown? God says these things to us in is love letter (aka the Bible):
Rest in the LORD, and wait patiently for Him;
Do not fret because of him who prospers in his way (Psalm 37:7)
In returning and rest you shall be saved;
In quietness and confidence shall be your strength (Isaiah 30:15)
In my experience, I’ve learned that God really does know best. I urge you to make rest a peaceful and well maintained priority.
