If you are not born again, then the "fulfilling of the Law", is not applied to you as a part of your Salvation/Redemption that is "the finished work of Jesus on the Cross".
If you are born again, then "Jesus has redeemed you from the curse of the Law"....by fulfilling it in your place, which abolishes for you.
This is why the born again are "not under the law, but under GRACE".
Problem is, there isn't a single passage in any 1 of the 4 gospel accounts that shows Jesus saying He came to live by the Law in anyone else's place. I do however, find a statement from Him in Matt. 5:18-20 where He says the Christian is going to be held solely responsible for securing their own salvation, which is echoed by Paul in 1 Tim. 6:12,19 and other passages.
To read Matt. 5:17 as "Do not think I have come to abolish the Law, but to abolish it by doing what it requires" is laughable, ignorant, absurd, and dishonest. If Jesus really came to do such a thing, then explain the various Acts passages that shows Paul saying he still believed in the authority of the Law and lived by it. Hyper grace propagandists can't have it both ways and say Paul did it because he was a Jew. If the Law was truly abolished as that camp claim, Paul wouldn't have lived by it at all.
Furthermore, if Jesus came to abolish the Law, then sins like incest, murder, adultery, witchcraft, and idolatry are no longer sins. Again, hyper grace propagandists can't have it both ways and judge the world by moral standards they believe were completely abolished by Christ. There isn't a single passage that says sins under the former covenant stopped being a sin under the current covenant just because Jesus' death gives a person the privilege of being reconciled to God.
Contrary to what the dishonest hyper grace propagandists expect others to believe, Jesus was not sent to die so people can continue doing the very things that He laid down His life for. That would mean Jesus allowed Himself to be ridiculed, beaten, and hung on a stake for absolutely nothing.
Paul's statement in 2 Tim. 2:19 makes it obvious that the Christian obligation is to live by the Law because he says everyone who professes Christ is obligated to depart from sin. And since the Bible defines sins as violating God's commandments(Jas. 2:10-11, 1Jhn 3:4), that means Christians are to do the exact opposite of violating those commandments as a way of life. There should be no confusion, nor should there be any professing Christians arguing against such sound and easy to understand theology.
