It’s remarkable how medical studies have proven this verse to be true. Practicing optimism or a peaceful heart is actually one way to improve your health. How can we take advantage of this truth? When you find yourself troubled with relationships, deal with the issues quicker. If you are fearful, lean into God’s promises and speak them out loud. If your stress levels are high, exercise to release the tension. Above all, work towards a peaceful heart through Christ.
A peaceful heart leads to a healthy body; jealousy is like cancer in the bones.
~ Proverbs 14:30 [NLT]
