With Jesus, no obedient believer is under the Law because Jesus asks us to keep His commandments which are in the Law. 

The parable of Lazarus and the rich man, along with other verses, teaches that the Law and the Prophets are still the guide to follow to avoid going to the hell to come.

Just because Paul says that we are not under the Law implies that we do not keep the Law. Paul is very upfront about keeping the Law and the role of the Law.

Romans 2:12-13 ASV
(12)  For as many as have sinned without law shall also perish without the law: and as many as have sinned under the law shall be judged by the law;
(13)  for not the hearers of the law are just before God, but the doers of the law shall be justified:

James 2:10 ASV
(10)  For whosoever shall keep the whole law, and yet stumble in one point, he is become guilty of all.

Romans 7:7 ASV
(7)  What shall we say then? Is the law sin? God forbid. Howbeit, I had not known sin, except through the law: for I had not known coveting, except the law had said, Thou shalt not covet:

Warning: The disguised ministers (deacons) of light of Satan claim that she should not concentrate too much in keeping the Law (sabbath or else) because doing so would mean that we are trying to save ourselves without Jesus! That is another lie of Satan. Because the commandment of holiness (Leviticus 20:7-8, 1 Peter 1:15-16, and in other verses), without which holiness nobody will see Jesus (Hebrews 12:14) commands us to be holy because the Godhead is holy. The circle of God is holy. We cannot be in Their circle we must be holy. If we are not holy God will not listen to us or gear us, according to John 9:31.

Pick any commandment to break to avoid being legalistic and you will not be saved because Ezekiel 33:13 and James 2:10 say that if you choose not to keep one commandment for whatever reason, God will forget all your good deeds or holiness and you will die and will be judged by the Law (Romans 2:12).

If you did not know that you were missing one commandment or that you had to keep an unknown commandment you will die without the Law (Romans 2:12).

So, logically, there must be a Law to keep if we will die for knowingly ignore a commandment or unknowingly do not keep a commandment.

Is there any commandment in Moses that someone teaches you not to keep? This person is a disguised minister of Satan (2 Corinthians 11:13-15).

The commandments that we are no longer obligated to keep are called the WORKS OF THE LAW which culminate to the annual day of atonement when all Israel start anew in justification and their 7 associated sabbaths.

Those commandments are mentioned in Colossians 2:16-17 which the disguised ministers of light of Satan used to fool gullible believers to not to keep the 7th day sabbath and to eat forbidden meat so that they will be partakers with Satan of the torments in the Apocalyptic lake of fire to come.

REPETITION
James 2:10 also implies that the Law is still in force by declaring that if we do all the Law but miss one law in it, we are guilty of all the Law. A guilty believer cannot be saved. A doer of the Law can be saved, according to Romans 2:12-13.

Be aware of the fact that, if we do not KNOW the Law and do something that the Law forbids or do not do something that the Law requires, our ignorance will not save us but that we will perish anyway.

Hence, we are to repent and start keeping the Sabbath because Jesus did not make any declaration which annuls the observance of the Sabbath.

When you hear your spiritual leader giving you some reasoning and not a verse which unambiguously annuls or approves a doctrine of the Old Testament, know that you are listening to the voice of Satan who deceived Eve by the same false reasoning blueprint to act contrary to what God (Jesus) says.

As Paul would say, I had not known breaking the Sabbath commandment, except the law had said, Remember the Sabbath day to keep it holy.
