David Plotz of Slate is undertaking a fascinating project with a terrible name: “Blogging the Bible.” It starts here and is a mix of snarky commentary and a close reading rooted in genuine curiosity. Both can be found in this passage:
“When He rejects the vegan special, God chastises Cain with this advice. ‘Sin couches at the door; Its urge is toward you, Yet you can be its master.’ This is just about the best advice you can give anyone. It is conservative idealism, compressed into a sentence: We must decide for ourselves to do right. Not that Cain pays attention: He kills his brother in the very next verse.”
