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

The answer is below

Explanation:

Because Bible assumed that with a merry heart, people would be able to follow God's rules and instructions. That is, to be cheerful might not be that easy to become, however, with a merry heart people would be able to believe that doing what God wants is for the greater good and the glory of God.

In short, the Bible emphasizes a merry heart as the way to be cheerful because it assumed a merry heart would always be obedient to God's will.

This is evident in Proverbs 17:22 which says, "A merry heart doeth good like a medicine: but a broken spirit drieth the bones."
