Vengeance is not always executed in a swift fashion (Ecclesiastes 8:11). In fact, believers often grow weary because the wicked seem to prosper in spite of their evil deeds. Yet, the Lord will execute vengeance in His time. The Bible speaks often of “the day of vengeance” to come. This day is very likely a thousand year period (2 Peter 3:8) which will begin shortly before the second coming of the Lord and will end at the great white throne judgment following the end of the millennial kingdom. It will be a time when the Lord will refuse to spare the wicked (Proverbs 6:34) but will set things right for the Jewish people (Isaiah 34:8; Isaiah 61:2; Isaiah 63:4).
Some Bible teachers have erroneously suggested that anger is a sin. But God actually commands His people to be angry, yet further instructs them not to allow that anger to push them to respond sinfully (Ephesians 4:26). If a man can be angry without sinning, then anger is not a sin. In fact, anger used in a righteous manner can accomplish many things for the Lord. One of the benefits of anger is found in today’s passage. A good, healthy, angry countenance can serve as the best remedy to keep people from backbiting others while in your presence. The reason people backbite others is because they have an audience for their vitriol. If we would express our displeasure, the backbiting would cease. Try it out! The backbiting tongue will cease the moment you respond with an angry countenance.
