I have told very willful lies to men, even after I received the Holy Spirit, and I didn't drop dead and He didn't abandon me. (Neither did He fail to bring them to my remembrance either though) I agree with them on this SOF - it was that they lied to the Holy Spirit as the verse says. They thought God didn't see. It was just some sort of game to them. That's my opinion though, based on the verse.
I wish they would correct with discussion and gentleness instead of what feels like...disdain and glee or pride or like...giving high fives for getting someone good. That's not how we share and learn. It just brings up a mans stubbornness and pride, or like you said, raises a mallet back at them.
Of course, that is just my opinion also.
