On your post #22 you posted the law wasn't to be discarded. Buggy responded with the NT disagrees with you. Perhaps he should have included either Jeremiah 31:31-33 or Hebrews 8:6-13 and Luke 22:20; 24:44. Maybe he gets tired of repeating himself with the self defined and limiting passages. There is more from Hebrews like Hebrews 10:9.
Yes, it's just a matter of properly understanding the grace vs law relationship, and why the OC became obsolete. With the OC what God demanded using the law wasn't
wrong; it was simply impossible for man to fulfill, and this was a lesson he needed to learn. The reason that it was impossible for man to fulfill is because man was
still wrong, i.e. still in an unjust state of being, not yet
justified IOW. And man's state of justice depends, first of all, not with being
sinless but in being in
a state of communion with God. So Jesus reconciles us with the Father first. He dies for our sins, so that now we're forgiven, our sins remembered no more (Jer 31:34) and we now come to know Him (also vs 34). This knowledge is the essence of our faith and communion with God and the life of grace He has for us to walk in. Now He may do a work in us (vs 32), of justifying us, something we're wholly incapable of doing on our own. Adam had thought otherwise, setting humankind on a path of prideful
self-righteousness, which we continue to struggle with in this life. The NC opens the door to "the righteousness of God", that justice that man was made for but which is only realized when he's in that state of communion with God, 'apart from whom man can do nothing', John 15:5. Now the law, which Jesus didn't come to abolish, can be fulfilled the right way,
with God. And this is why Rom 2 can tell us that, while the law cannot
justify us, we'll nevertheless be judged by it. Only God can justify us; only God can make man just, the being he was created to be. Our job is to become jaded with what the world offers, a life without God, a life where man's will reigns together with all the sin and evil that results, so that we may turn from our pigsty and run to the One who we finally know our need of, and who's now been fully revealed, when the time was ripe in human history, by our Lord Jesus Christ.
