I was referring to some of the commenters but I can see why you might have misunderstood. Apologies for that.
Although I do think your article makes the mistake of assuming that all the actions of the Bible’s heroes are condoned simply because they were seen as heroes. It seems clear that it’s supposed to be a mesasage of grace — that despite their failings, their sin, their disobedience, God remained faithful.
I’ve been reading the books of Samuel lately and have noticed that David comes across as far less than perfect and it implies that his polygamy in particular and his weakness in the sex department cost him. Yet despite his brokenness, he is still seen as a hero — perhaps because he faced his brokenness and admitted it in the end.
