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).
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.
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.
Sometimes the most effective means of defining a Bible word involves researching those words commonly associated with the word in question. Delicate is such a word. On four occasions, the Bible associates the word delicate with variations of the word tender (Deuteronomy 28:54, 56; Isaiah 47:1). This association provides the Bible student with the sense that a delicate person is easily broken spiritually. Additional Bible study demonstrates that a tender heart remains pliable and prone to brokenness before the Lord. Conversely, the Bible points to a hardened heart as remaining obstinate. The word obstinate conveys an inflexibleness or stubbornness. As believers, we should aspire to be tenderhearted before the Lord with a heart easily moved to accomplish His will.
