Sometimes the most difficult and significant tasks involve the simplest truths. For instance, every Christian should quickly learn that vengeance belongs unto the Lord. God confirms as much throughout scripture (Deuteronomy 32:35; Psalm 94:1; Romans 12:19; Hebrews 10:30). This should be understandable as only the Lord has all the necessary information to execute just vengeance 100 percent of the time. When man attempts to execute vengeance, he often does so out of an improper motive or without key information of the evil that appears to have been done. Furthermore, when a believer takes vengeance into his own hands, he robs the Lord of His right and responsibility to exact vengeance at the right time and in the right manner.
God is love, but that does not mean that everything that people love is of God. Today’s verse warns believers not to love the world or the things that are in the world. God’s people are repeatedly admonished about this because believers are prone to love things and people contrary to the will of God. The Christian’s heroes are generally no different than the world's heroes. We have many Bible examples of men who loved those of whom God disapproved. Samson exemplified this in his love for Delilah (Judges 16:4). Amnon had an unrighteous love for his sister Tamar (2 Samuel 13:1). Solomon failed in this area by loving “many strange women” (1 Kings 11:1). Demas left the ministry because he “loved this present world” (2 Timothy 4:10). Unfortunately, the heart of a believer can be drawn to love things and people displeasing to the Lord. It is always important to consider the object of our love and refuse to make excuses when we know better.
