God expects loyalty from man. He is not interested in “worship” that involves Him being one of man’s many gods. In fact, He adamantly opposed this position within the Ten Commandments. There the Lord admonished His people to “have no other gods before” Him (Exodus 20:3). He then warned them not to make nor bow in worship to idols (Exodus 20:4-5). The Lord earned Israel’s loyalty in many ways, but the Bible specifically points to His delivering them from Egypt. It is important to note that God does not expect blind loyalty from man, but He certainly deserves this type of loyalty. He earned man’s loyalty by being his Creator. Yet His ultimate claim to loyalty stems from His offering to redeem fallen man though man is completely unworthy.
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.
