Talking about the love of God is far more popular than talking about the wrath of God. Most preachers would prefer ignoring it in preaching and most people of the pews would rather not hear it mentioned in preaching. The common consensus is to stay focused on positive and uplifting things. The only problem is that the Bible speaks often of the wrath of God. Romans 1:17 reads, "For the wrath of God is revealed from heaven against all ungodliness and wickedness of those who by their wickedness suppress the truth." The problem of a God of wrath is compounded by another word Paul wrote a little later in the letter, "But now apart from the law, the righteousness of God has been disclosed..." (Romans 3:24)
The Word of God calls us to live with the tension created by holding in the same hand "the wrath of God" and "the righteousness of God." Understanding the wrath of God is more difficult than understanding the righteousness of God. The wrath of God is not about vengeance, or uncontrollable anger, but about the justice of God. The wrath of God is empty of grace as it is about evil getting what evil deserves. Even as the wrath of God is empty of grace so is it empty of the lovingkindness which is implicit within the Old Testament word, "hesed." It is hard for us to think of God in such terms.
John the Apostle wrote, "...God is love...(I John 4:8, 16). Of course, nothing makes this truth clearer to us than the presence of Jesus in the flesh in our world. The righteous God who is disclosed to us is one of love. He is one filled with lovingkindness. He is one who gives the free gift of grace. Thus, we live midst a mystery filled with theological tension that is not about choosing one or the other, but both.
