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.
Most saved women who have an unsaved spouse would testify that their chief concern lies with seeing their husbands come to know Christ as Saviour. The context of today's passage reveals how an unsaved husband can be won to Christ through his wife's actions. Displaying a meek and quiet spirit is paramount in such efforts. This meekness is to be worn and displayed much like an ornament, and such a spirit is of great price in the sight of God. Most women who are married to unsaved men will admit that their husbands tend to treat them with a lessening degree of devotion as the marriage ages. Regardless, the Bible admonishes wives in this situation to respond in meekness toward their husbands with the goal of winning them to Christ. Today's passage specifically applies to wives with unsaved husbands but also has far reaching application to all believers.
