Confusion Arises About the Law Today Because Many Christians Today are Unaware of the Heresy of Circumcision Salvationism (During that Time Period):
Some Christians here do not understand that Paul was trying to refute "Circumcision Salvationism." For there were certain Jews were trying to seduce believers into thinking they needed to be circumcised in order to be saved. This is evident that this was taking place because of certain clues we find in Scripture.
1 "And certain men which came down from Judaea taught the brethren,
and said, Except ye be circumcised after the manner of Moses, ye cannot be saved.
2 When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question." (Acts of the Apostles 15:1-2).
"...there rose up certain of the sect of the Pharisees which believed, saying, That it was needful to circumcise them, and to command
them to keep the law of Moses." (Acts of the Apostles 15:5).
"Forasmuch as we have heard, that certain which went out from us have troubled you with words, subverting your souls, saying,
Ye must be circumcised, and keep the law: to whom we gave no
such commandment:" (Acts of the Apostles 15:24).
"What advantage then hath the Jew? or what profit
is there of circumcision?" (Romans 3:1).
"For neither they themselves who are circumcised keep the law; but desire to have you circumcised, that they may glory in your flesh." (Galatians 6:13).
3 "But neither Titus, who was with me, being a Greek, was compelled to be circumcised:
4 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage:" (Galatians 2:3-4).
2 "Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing.
3 For I testify again to every man that is circumcised, that he is a debtor to do the whole law.
4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
5 For we through the Spirit wait for the hope of righteousness by faith.
6 For in Jesus Christ neither circumcision availeth any thing, nor uncircumcision; but faith which worketh by love." (Galatians 5:2-6).
The Law has changed:
Scripture says the Law has changed.
"For the priesthood being changed, there is made of necessity a change also of the law." (Hebrews 7:12).
It's why we are to SERVE in newness of spirit and not in the OLDNESS of the LETTER (i.e. the Old Testament Law of Moses).
"But now we are delivered from the law, that being dead wherein we were held; that we should serve in newness of spirit, and not in the oldness of the letter." (Romans 7:6).
Granted, there are moral laws that have been carried over into the New Covenant and it's commands. It's why Paul says that the law is good if one uses it lawfully (or correctly).
"But we know that the law is good, if a man use it lawfully;" (1 Timothy 1:8).
So Paul was not against the keeping of the Moral Law (like: Do not murder, do not steal, and do not covet, etc.) as a part of God's grace. Paul never once said we can break God's Moral Law and still be under God's grace. On the contrary, Paul essentially says that if we break the Moral Law, we have no inheritance in the Kingdom of God (See Galatians 5:19-21). Paul says we can deny God by a lack of works (Titus 1:16). Paul says if any man speaks contrary to the words of Jesus Christ and the doctrine according to godliness, he is proud and he knows nothing (1 Timothy 6:3-4). James says God resists the proud and gives grace to the humble. This makes sense because Jesus said the pure in heart will see God (Matthew 5:8). A person who is trying to justify in remaining in their sins is not pure of heart and humble.
