God is angry, in fact He is taking vengeance against Edom. Vengeance is a harsh word, especially in relationship to a loving, compassionate and forgiving God. “Vengeance” is a harsh word; it means “to get back,” “to compensate for loss or harm suffered.”
For the Lord has a day of vengeance, a year of retribution, to uphold Zion’s cause. (NIV)
There comes a time when God must act against those who continually provoke Him to anger by coming against His people and His land of Israel. In other words, there will come a time when God will “get back against the nations (unbelieving Gentiles”) for the harm done to Him on behalf of Israel.
PRAY FOR YOUR CHURCH TO TEACH THE TRUTH ABOUT ISRAEL.
