(Lot, you’ll remember, is the brother of Abraham, who, with his family, was ordered by God to flee Sodom and Gomorrah, two cities God decided He needed to destroy because, Elder Holland explains, God had “had as much as He could stand of the worst that men and women could do.”)
What Elder Holland says the verse means, at least here, at least in one context, is this:
Apparently what was wrong with Lot’s wife is that she wasn’t just looking back, but that in her heart she wanted to go back. It would appear that even before they were past the city limits, she was already missing what Sodom and Gomorrah had offered her. . . . In short, her attachment to the past outweighed her confidence in the future. That, apparently, was at least part of her sin.
