Hope for the wicked

The second line of interpretation acknowledges that prophetic intercession is highly effective in God’s outworking of His plans. Precisely because of its power on swaying the divine mind, Yhwh has to prohibit His prophet to intercede in order to execute His judgment. By implication, this sort of reading would suggest that even when the people’s sins are as great and many as in Jeremiah’s days, the prophetic intercessor could hope to pacify the justified wrath of God and persuade Yhwh to show leniency and to withhold punishment from the sinful party.— Standing in the Breach, page 433

That's assuming, of course, that there are people willing to intercede!
