There is a certain kind of heresy to which it is important to respond that, no matter what you achieve through your best efforts, you cannot be good enough to earn a place in heaven.

But for most of history and most of the human race, as any parent with more than one child knows, the issue is not whether anyone can be good enough.  The issue is that people think that evil is good.  They think that they are supposed to behave in certain ways involving boasting and rivalry and a demand for immediate recompense for any slight against them.

So for most of history and most of the human race, the simple story of how God acts in human circumstances, and his instructions to embrace new ideals of peace and reconciliation, is amazingly good news.
