He gave a very physical law. we can't pretend circumcision wasn't meant to be carried out. i'm not sure you're addressing my question:
why these carnal commandments instead of grace and truth ? the law says, do these things and you will live by them, but the scripture says, life cannot be attained by these things; the law is not of faith. the law as a guide, guides us to Christ - and in Him we have joy and life and peace, but in the law, we do not. we have curse & death. coming to Him, we die with Him, and die to the law, being set free from it, and have life. a Torah was not given that could impart life.
so why was the bondage of the law given ?
why not a law that actually could impart life, if such a thing could even exist?
Paul's definitely talking about Torah when he says "the law" -- don't be silly. he doesn't presume to break it into pieces, keep some and delete the rest. thinking so that is how to 'distort' his writings, to destruction ((2 Peter 3:16))
