Proverbs 17:22 (NKJV)
A merry heart does good, like medicine,But a broken spirit dries the bones.
Doctors know that a pleasant and good outlook on life full of hope will do as much to help a person get well as any amount of medicine. And it is true too, that people can become physically sick as a result of mental depression. What can make someone merry? Good news, and the best news is that God has made a provision for the forgiveness of sins and for us to be able have eternal life. Not just when we get to heaven but here and now too.
