The reason works of the law can't justify is because no one keeps the law.
I trust you understand that this begs the question. I get the impression that
perhaps, repeat perhaps, you are not aware of the fact that
only Jews were under the Law of Moses. Many Christians mistakenly believe otherwise.
Now: Since only Jews were under the Law of Moses, Paul
could, repeat could be saying
this (as opposed to what
you think he is saying): Works of the Law can't justify
because that would limit salvation to Jews. And, I suggest the following bit from Romans 3 powerfully shows that this is
precisely Paul's argument:
For we maintain that a man is justified by faith apart from works of the Law. 29 Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also,
Now here I am
making a case (not merely stating a position and thereby begging the question). Let's be clear about something. To say "you cannot be justified by doing the works of the Law of Moses" is
not, repeat
not the same thing as saying "
you cannot be justified by doing the works of the Law of Moses because no one can keep the law", which seems to be what you are saying. An objective reader will know there is another possibility:
you cannot be justified by doing the works of the Law of Moses because that would limit salvation to Jews.
I have just provided evidence that the 2nd concept is at the core of Paul's thinking.
And an obedience which also determines the quality of your entrance into the kingdom.
In Romans 2:6-7, Paul does not say you get rewards or "quality" according to what you have done, he says you get
eternal life according to what you have done.
If, repeat
if, you are one of those who say that 2:6-7 is about getting rewards over and above eternal life,
then you have already left the playing field in the sense that you have let it be known that you are willing to
change what a text actually says in order to force into a position you hold.
Have you left the playing field? Are you one of those who is willing to re-write 2:6-7?
