Why do you think the Bible emphasizes a merry heart as the way to be cheerful?

Explanation:

Proverbs 17:22 tells us, "Proverbs 17:22 tells us, "A merry heart doeth good like a medicine: but a broken spirit drieth the bones " . The person with a joyful heart, obeys God and follows His Word. People with a joyful heart know that God's instructions in the Bible may not always be easy to follow- but they trust that they're there for a reason, that they are divinely inspired and are for our good and God's glory.
