We enjoy seeing people get punished. How often have you heard, "He got what was coming to him"? It makes us feel good when the evil get repaid for their dastardly deeds. And the verse above gives us a reason to swell in pride as we shake our bony finger at those who lie and connive to cheat others.
Before we get too carried away, perhaps we should see what Jesus has to say - But I say unto you, That every idle word that men shall speak, they shall give account thereof in the day of judgment. For by thy words thou shalt be justified, and by thy words thou shalt be condemned. (Matthew 12:36-37) Notice, Jesus didn't require evil intentions for us to be responsible for our words. Any words, intentional or idle, will be accountable on the day of judgment.
We need to renew our focus on our words and deeds. Even if they are idle, they are a reflection of our heart. Are we reflecting human nature or God's love? We will be held accountable, so let's assure our actions reflect the One who lives within us.
