God is not a cosmic killjoy. I know some people who believe He is. They think God runs around saying, “There’s one having fun; get him!” They believe God wants to rain on everybody’s parade. But that isn’t so. God made you. He knows how you operate best. And He knows what makes you happy. The happiness He gives doesn’t stop when the party’s over. It lasts because it comes from deep within.
John MacArthur
