‘…To bless your enemy is to speak well to him and about him. How might you control your speech when speaking to the offender? How might you control your speech when speaking to others about the offender? Let the Scriptures guide you: “Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen” (Ephesians 4:29; read this especially in light of God’s grace toward us described in Ephesians 1-3). “Reckless words pierce like a sword, but the tongue of the wise brings healing” (Proverbs 12:18). (I often recommend counselees in this situation meditate on Proverbs 10 and 12, the two most concentrated chapters in Proverbs on godly speech.)’
