A merry heart maketh a cheerful countenance.
A person who is happy inside has a happy face too. And who could be happier than a Christian? Just think - your sins are gone, you have a home in heaven, and you have a Savior who cares for you and wants to bless you. That will produce a happy heart. Does this mean no troubles? No, of course not! But with Jesus in your heart and a deep-rooted happiness inside you, you have what it takes to overcome in the trouble. As the song says, “Don’t worry! Be happy!”
