Re: sins of the father (visited upon the sons to the 3rd & 4th generation)
The 7th Generation, if understood as one's own subsequent 6th or 7th reincarnation, is far more likely to hit you squarely IN THE FOREHEAD before you go and do something offensive, stupid or unnecessary (even if impacting primarily you and only you) ...
... than if you're just sitting around feeling sympathetic about those poor bastards - or in this case - non-bastards ... coming down the line.
I don't care HOW MUCH you love your own family, or your own flesh & blood. Apparently that doesn't mean JACK if you're Republican, Tea-bagging it or convinced you're some kind of war hero (aka survivalist? what do these idiots call themselves now? you know, the self-deluded `patriots').
The bottom line? If told that "you are screwing things up for yourself," then this is the surest way to get people to see the foolishness of their actions. Go back, reread with this understanding ... and this teaching will make by far a great deal more sense than if we try to bend and fit the scriptures to our modern-day, secularized, watered-down and more convenient interpretations.
I'm not denying that what we does impacts every other being on the planet, your own family included - and quite often, soonest. I'm just showing that there is a deeper, more direct meaning which this 7th generation business has always referred to. If it doesn't mean the same thing yet to and for you ... just give it awhile. Come back to it later. See if your take on things hasn't changed.
