The best way to deal with slander is to pray about it: God will either remove it, or remove the sting from it. Our own attempts at clearing ourselves are usually failures; we are like the boy who wished to remove the blot from his copy, and by his bungling made it ten times worse.
Author: Charles Spurgeon Source: The Treasury of David, Commentary for Psalm 119:20.
The joyless Christian reveals himself by having negative thoughts and talk about others, in a lack of concern for others welfare, and a failure to intercede on others behalf. Joyless believers are self-centered, selfish, proud, and often vengeful and their self-centeredness inevitably manifests itself in prayerlessness.
