There are probably a few hundred reasons that might motivate you to care for yourself and to be healthy. Here are five, actually four, reasons that motivate me at a really deep level… and I think that these are reasons why God would want us all to be motivated by.

  1. It glorifies God
  2. You’re taking care of your body –  His temple
  3. It’s being a good witness
  4. You’ll have more energy – be better equipped for what God has planned for you

2 Chronicles 30:22
Hezekiah encouraged all the Levites regarding the skill they displayed as they served the LORD. The celebration continued for seven days. Peace offerings were sacrificed, and the people gave thanks to the LORD, the God of their ancestors.
Note: One important purpose of the peace offering was to express gratitude to God for health or for safety in times of crisis.

If our motivation for attending to our health is pure before God, it will be pleasing to him. Then, as we call to him to help us with aspects of caring for our bodies, he will hear our cries and attend to them. Psalm 34:15
