Proverbs 12:6-7 (ESV)
6 The words of the wicked lie in wait for blood,
but the mouth of the upright delivers them.
7 The wicked are overthrown and are no more,
but the house of the righteous will stand.
Those who are wicked use their speech to entrap and harm. But those who are upright communicate words of salvation, undoing the destructive messages of the ungodly. In the end, God ensures that his words, taught to a dying world, will bear fruit. God is aware of all that takes place in the universe. Those who desire to use their words to harm others will end up harmed themselves. The followers of the Lord, who hear the gospel, rightly respond to it, and put it into practice, will not be shaken, even in the final judgment. The Lord frowns upon those who seek to damage the reputation of others by using gossip or slander. How do you speak about your enemies? Do you tear them down before others, or do you bless them and speak kindly about them instead? God is opposed to those who desire to see the downfall of others, especially fellow believers.
