Many people think that a Christian is one who goes through life hanging his head, heaving sighs, wearing a long face, and looking very solemn. This is one of the biggest and most widely believed lies Satan ever invented.
Real, lasting happiness is the portion of every believer. "Gloomy!" What is there in the Gospel calculated to make one gloomy? Does it make a man "gloomy" to know that all his sins are forgiven? Will it make one "gloomy" to be assured that he will spend eternity with the Lord Jesus in glory? Will the condemned criminal who has been pardoned, feel sad?
The only one who has a right to be happy is the Christian. He alone is delivered from the bondage of sin, death and judgment.
