James Montgomery Boice on Nahum 1:2
Many people do not like to think of God as a God of wrath. They prefer to think of Him as a God of sickly love and sentimental indulgence. What a weakening of the biblical concept of the only true God that is! It is true that God is a God of love and mercy – a holy love and an utterly undeserved and sovereign mercy. It is also true that God is a God of wrath against sin.
