My brethren, count it all joy when you fall into various trials, knowing that the testing of your faith produces patience.

James 1:2-3


Lament and mourn and weep! Let your laughter be turned to mourning and your joy to gloom. 10 Humble yourselves in the sight of the Lord, and He will lift you up.

James 4:9-10



One could easily get the impression from James 4:9-10 that James is against joy, that the Christian life is a life of constant sorrow. In context, James is commanding Christians to mourn their sins. He is addressing people who are laughing when they should be crying.
