What does Proverbs 15:30 mean?

The phrase "the light of the eyes" refers to a happy expression. The characteristic look of a person's eyes when they smile fits this description. In fact, in English, a person with a large smile is said to be "beaming." When a person greets others with a big smile, they feel uplifted and joyful. Paul understood how joy strengthens Christian bonds. He urged the Philippians to rejoice in the Lord (Philippians 4:4). Two members of the Philippian church, Euodia and Syntyche, were not getting along with each other. They needed to "agree in the Lord" (Philippians 4:2) and rejoice instead of bearing a grudge.

Just as a warm, welcoming look can make a person feel better, so too does good news. There is only a thin separation between one's emotional health and physical health. Good news encourages those who receive it, and in turn the encouragement promotes physical well-being. Although Christians are not immune from disease, aches, and pains, the lifestyle which naturally comes from following God's will gives a better chance at health than avoidable sickness or injury.. Much of this is due to avoiding the natural penalties of sinful living, including the effects of chemical abuse and risky behavior. The good news of the gospel and the good news of the promises in the Bible lift a believer's spirits and contribute to good physical health.
