Skilled in doing Evil
The people of Jeremiah’s day were used to the late summer breezes blowing hard. They separated the chaff from their grain by tossing it up into this September wind. They weren’t used to storms coming in fall and bringing devastation. They were used to petty wars and raiding parties worrying their borders, they weren’t expecting the well disciplined armies of Nebuchadnezzar and the loss of their nation. In a similar way, people today are used to an occasional bout of bad weather, but we are slow to accept the global consequences of climate change.
