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.
In the midst of suffering, Christians can fail to rejoice in future blessings resulting from obedience. Additionally, the trials of life can cause one to lose focus on the unseen future blessings. One such case involves rightfully leaving vengeance to the Lord (Romans 12:19). God's blessings are frequently not seen or realized until much later. The meek who leave vengeance to the Lord have God's promise that "The LORD lifteth up the meek" (Psalm 147:6). Nevertheless, a believer living a meek life may become disheartened by those who take advantage of kindheartedness. In fact, a meek and compassionate believer may appear weak in the eyes of the world necessitating the Lord's deliverance (Psalm 76:9; Psalm 149:4). In the end, the Lord will deliver (Psalm 76:9), lift up (Psalm 147:6), beautify (Psalm 149:4), and bless (Matthew 5:5) the meek. It is important to remember that the future blessings following life's temporary trials are worth forgoing the immediate pleasures that might come from taking matters into our own hands.
The Bible repeatedly referred to Christ's meekness during His interaction with others. Meekness implies a gentle response toward those who attack. Jesus Christ demonstrated meekness to its perfection on the cross of Calvary when He said, "Father, forgive them; for they know not what they do" (Luke 23:34). Peter emphasized this point when he said of Christ, “Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously” (1 Peter 2:23). Isaiah prophesied of Christ, “He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth” (Isaiah 53:7). The Bible says that Jesus was mocked, spit on, and struck by His accusers, yet He displayed incomprehensible meekness.
