A difficult thing to understand

“Behold, I am  against you, O most haughty one!” says the Lord God of hosts; “For your day has come, the time that I will punish you.”  Jeremiah 50:31

It is a difficult thing to understand—the wrath of God.  If His wrath were only ever expressed in a passive, indirect way, it would be easier to deal with.  But is that true?  The flood, the fire that fell on Sodom and Gomorrah: Passive?  Indirect?
