What is taught and what actually happens...
is that one's salvation isn't dependent upon keeping the law
...is that, in the end, God is your (the) judge, yes?
I mean, teachings are from, whether they be that you WILL go to hell for X or MIGHT, the word of man teaching to you the WORD as he understands it, right?
And at the end, all teachings agree that it is His will, His judgement as to whether you go to hell for wearing pants or not, yes?
Therefore if we all agree that what you are taught comes from man as he has learned the Word and we all agree that man is imperfect and we all agree that final judgement is up to the Lord then we can all agree that He will very likely pass His judgment on an individual based on that individual as a whole and not necessarily for specific violations per se of what you were taught as THE Word of God seeings how you were taught by an imperfect creature; man.
Perhaps it is silly to teach things as absolutes but that is imperfect mans job as willed by the Father, to teach as best he, man, can. It would, however, be far sillier, having accepted that man, in his limited capacity, must teach and can only teach as he understands it, to then somehow presume that the Lord is bound in his actions by the word of man, yes?
In other words, though the rules be what they are, when it comes to judgment...
Father knows best.
