James 4:9

Why does James say this? He writes to them, telling them to weep and mourn. Apparently, they are to have this attitude towards their sin. It's not as if we're to simply ignore our sin. We aren't to go about being happy about our sin. We must ensure we have the correct response to our sin, and that is to weep and mourn. Too often perhaps we're happy or joyful over our sin, but let it not be so.
