The Declaration of Independence says that all men are entitled to life, liberty, and the pursuit of happiness. Life and liberty seem doable. But the writers of the Declaration tell us that happiness is not so certain. It is a pursuit.
Our world is looking for joy. But joy is not easily found. We live in a joyless, bitter, and angry world. But that was why Jesus was born. He was born to bring joy from heaven to earth. It is through him that joy comes down to us.
