People in the world are generally quite self-centered. Even saved people are often lovers of their own selves instead of preferring one another.
Sometimes the most difficult and significant tasks involve the simplest truths. For instance, every Christian should quickly learn that vengeance belongs unto the Lord. God confirms as much throughout scripture (Deuteronomy 32:35; Psalm 94:1; Romans 12:19; Hebrews 10:30). This should be understandable as only the Lord has all the necessary information to execute just vengeance 100 percent of the time. When man attempts to execute vengeance, he often does so out of an improper motive or without key information of the evil that appears to have been done. Furthermore, when a believer takes vengeance into his own hands, he robs the Lord of His right and responsibility to exact vengeance at the right time and in the right manner.
A simplistic view of vengeance involves the retribution of an evil deed. The first (Genesis 4:15) and last (Jude 7) mention of the word vengeance substantiates this definition. The Bible uses words like recompence (Deuteronomy 32:35), reward (Deuteronomy 32:41), punishments (Psalm 149:7), avenge (Jeremiah 46:10), revenge (Ezekiel 25:15), and repay (Romans 12:19) as descriptive words for vengeance. With this in mind, it is clear that vengeance is the just punishment as a consequence upon those who violate the laws of God. It is not the dispensing of wrath without cause but is specific punishment exacted for specific crimes committed.
God's children are supposed to be easily recognizable through their love one for another (John 13:35). Today's passage teaches Christians to be both kind and forgiving. In the midst of these two exemplary qualities, the Lord desires His children to show forth a tender heart. This means that our hearts ought to be easily moved when other believers are experiencing either joy or distress in their lives (Romans 12:15). Unfortunately, instead of exemplifying a tender heart, far too many believers are becoming more like the world by displaying a divisive spirit and by devouring one another (Galatians 5:15). Believers who are hard-hearted toward others are generally hard-hearted toward the Lord as well (1 John 3:17).
