You don’t feel good, so you snap at your spouse. You’re tired, so you make a quick unwise decision you later regret. You wake up with a headache, so you try to sleep in, and skip your morning quiet time.
Our physical health impacts every other area of our lives. If you are in shape, at a healthy weight, with good nutrition, and well rested, you are a comparatively formidable force against any obstacle in your way. You will have the mental energy to be creative and efficient at work, be fully present for your spouse and children, problem-solve well in a crisis, and have the spiritual energy to grow in your relationship with God.
On the other hand, if you are sick and tired, overweight, full of junk food, and never exercise, you have no reserve to handle even the “normal” stuff life throws at you. With no energy to draw on your work productivity will decrease, your personal relationships will be contentious, your mind will function more slowly in a crisis, and you won’t have any strength left for spiritual growth.
