In junior high school, my math teacher said something shocking. In front of our whole class he said, “Marilyn, you are like a lump on a log.” That’s a great illustration of reviling. It is name calling.
Various verses in the Amplified use these words: insult, wound us with an accursed sting, scoff, sneer at, railing, and slandering. 1 Peter 3:9 says that when people revile us we are to do the opposite ~ bless.
My dad was a righteous name caller. He would call someone. When they answered, he would say, “Saint” and say their name. Paul often began his letters addressing the saints. Ephesians 1:1 says, “…to the saints who are in Ephesus….” Every believer is called a saint.
Reviling is a pronouncement. If you have been called something that you aren’t, I encourage you to forgive that person. Then renounce (disown) what they spoke over you. Next declare who you really are in the eyes of the Lord. Then ask the Lord to bless that person with what they obviously lack. That is coming in an opposite spirit ~ canceling the reviling.
