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.
Following a shipwreck, Paul, and those with him, escaped to an island called Melita. The Bible describes the natives as a barbarous people who were not completely void of truth. They demonstrated kindness toward those who had escaped the sea by kindling a fire for them. Paul helped the natives by gathering a bundle of sticks to cast upon the fire. As he cast the sticks on the fire, a viper came out of the heat and fastened on Paul’s hand. Immediately, the barbarians assumed Paul to be a murderer who was being recompensed for his wickedness. Even though these people did not know the Lord, they had some of His laws written in their consciences..
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).
No sensible person would ever ask to be on the receiving end of the wrath of God. The thought is completely illogical! Yet, this scenario takes place every day in the lives of those who live with hardened hearts toward the things of God. The Bible affirms that a humble spirit begs God's attention and brings His corresponding blessings (Isaiah 66:2). Contrariwise, a hard heart also garners God's attention but for judgment rather than blessing. Today's passage points out that the hard heart treasures up wrath against itself. This wrath rarely takes place immediately, but it will come in the “day of wrath.” It is important to recall that hardness of heart brought the plagues upon Egypt and it brought blindness to the Jews in Jesus' day. Ultimately, it will bring eternal damnation in the lake of fire to all those who fail to accept God's payment for sin.
