what being apart from the law means.

[FallentoReason]

If there were people literally dying of thirst, and they were all standing before a water fountain that only works if the knob is turned clockwise, but the person in front dying of thirst will only turn it counter clock wise, and as a result get no water. Angered, he turns to the crowd and say to move on, the water fountain is broken..

I like how your analogy combines "sour grapes" and "you can lead a horse to water but you can't make him drink." Or you can lead an atheist to the Living Water, but you can't make him accept.

Such a loose argument cuts both ways; you can lead a religious person to reasons why they're irrational, but you can't make them accept those reasons.
