I read about a guy who described an evening when he was browsing through an old newspaper. He found an article about men losing their memory cells faster than women. He read it aloud to his wife.
"It must be true," she said. "This is the second time you've read that article to me."
In most cases, a loss of memory is not a good thing. Here is one exception, when God voluntarily loses His memory:
… “I'll forever wipe the slate clean of their sins.” Once sins are taken care of for good, there's no longer any need to offer sacrifices for them (Heb. 10:17) [THE MESSAGE].
