Scripture plainly reveals that God repeatedly calls for His people to separate from the world. This separation extends to every aspect of life, especially including the marriage bond. Why? Because God knows the very real danger that unbelievers pose to believers by drawing them away from Him (Deuteronomy 7:3-4; Judges 3:6-7; 1 Kings 11:2). This is why God specifically instructed His people in both the Old and New Testament to marry among themselves (Jew with Jew and Christian with Christian). The nation of Israel was forbidden to yoke up with the surrounding nations because Israel would adopt heathen practices and the worship of false gods (Exodus 34:15-16). Though God’s commands for the New Testament believer are often different from His plan for the Jew, in this aspect they remain constant and unchangeable.
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).
