Do we still have to obey the 10 commandments?

I have lost count how many times this has been asked here.

The 10 Commandments are identified as being the old covenant; a legally binding agreement between the two parties, God and the then nation of Israel, with a provision to continue with their progeny after them upon undergoing circumcision. 

"We" who are all alive today, are not a legal party to that covenant, which ended upon the death of the party of the first part, God, in the Personage of Jesus who was the God of that old covenant Incarnate. Death terminates such covenants, and the apostle Paul weighs in on this in Romans chapter 7.

That covenant had the potential to be fulfilled prophetically and literally. That covenant required, ultimately, a death penalty for sin, which Jesus fulfilled in the stead of all mankind upon their repentance.

We do not "obey" them as a covenant law.  Regarding the Sabbath, the way it was kept holy was through the additional sacrifices required on that day, according to the law. 

There are three prophesies in the OT writings where God said He would take away the Sabbath, which He did, in a number of ways, including the way the Sabbath was determined with a lunar calendar, where the week was reset every new moon. We now use calendars with fixed weeks. The Sabbath of the Bible wanders through our fixed week calendar, so that it can fall on any day of the week when juxtaposed with the ancient lunar calendar Israel used for millennia. 

The Sabbath is Friday night at sundown to Saturday night when three stars come out. You already blew that commandment with your Sunday worship. HA HA.

Still? You never had to, sillyhead. You were TOLD by a pair of ancient books of mythology that you had to, but you didn't ACTUALLY have to. Come on, you understand that, dontcha?

I try to observe the top 5 

“Thou shalt not bear false witness against thy neighbor... , Thou shalt not covet thy neighbor’s wife or pay the porn star for silence if you are married, “Thou shalt not covet thy neighbor’s goods.” and say you will use the money on a charity or for some University but use it for your political race funding... now by some Christians standards can make you a good president... so yes Gee Zeus

Great question. I don't work of the Saturday because I always remember God blessed the 7th day from the begining of creation. He also rested on it and made it Holy. But I know God doesn't chanege. Keeping the commandments is love. That's the love that Jesus wants us to show to God and everyone. We aren't loving God if we bow down to idols and worship them and we arn't loving God ifwe take His name in vain. We aren't loving God if we have another God above Him. I mean. The 2 great commands is love God with your entire being and love your neighbor as yourself. If you love you neighbor you woun't kill them, steal from them, lie to them, covet their things, commit adultry with thier husband or wife. I mean it seems to me that's it's common sense to someone who has Gods Holy Spirit in them that they are now on a different leven than everyone else. You no longer live according to the Flesh that wants to do these things but you should be living according to the Holy Spirit that's in you that gives you it's power to keep you from doing those things. But I really don't know to be honest about the sabbath. I know I don't keep it perfect but I just don't go to work and try to not do my own pleasures on that day. I say it's even more than the 10 commandments but it's easy because Gods Spirit is in you guiding you that's if you have it. You don't have to force yourself it should happen naturally. Sorcery isn't in the 10 commands but it's in other verses as a sin that will send people to hell. Gods Spirit will guide you.

Matthew 19

16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?

17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.

18 He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness,

19 Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.

Mark 7

20 And he said, “What comes out of a person is what defiles him. 21 For from within, out of the heart of man, come evil thoughts, sexual immorality, theft, murder, adultery, 22 coveting, wickedness, deceit, sensuality, envy, slander, pride, foolishness. 23 All these evil things come from within, and they defile a person.”

1 Corinthians 3:17

16Knowe yee not that yee are the Temple of God, and that the Spirit of God dwelleth in you? 17If any man defile the Temple of God, him shall God destroy: for the Temple of God is holy, which Temple ye are.

Revelation 21:8 But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.

Mark 12

29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord:

30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.

31 And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.

1 Corinthians 6

9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,

10 Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.

11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.

Galatians 5:21

18But if ye be led of the Spirit, ye are not under the law. 19Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, 20Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, 21Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God. 22But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, 23Meekness, temperance: against such there is no law. 24And they that are Christ's have crucified the flesh with the affections and lusts.

Mark:12

30. And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.

31. And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.

Jesus in essence replaces all other scriptures with 2 verses:

Sure, because of Jesus Christians are permitted to lie, steal, murder, envy, commit adultery, break the sabbath, etc.

It would explain why people who are religious Christians do those things every day.

Old Testament law included many dietary regulations which were instituted as a preparation for his teaching on the moral law. Jesus discussed these laws and abolished them: 

“Hear me, all of you, and understand: there is nothing outside a man which by going into him can defile him; but the things which come out of a man are what defile him.” (Thus he declared all foods clean.) (Mark 7:14-19)

So Jesus abolished the cleanliness and dietaryTorah laws. The 10 Commandments are part of natural law, which means they are for all times and for all peoples.  That means Christians are required to follow them. Jesus did away with dietary laws, he didn't do away with natural law

The TC were part of the OT which was superseded by the NT (Heb 8:7,13).  Some commands from the OT were carried over into the NT, but some were not.  When it comes to the TC, nine of the ten were repeated, whereas remembering the Sabbath was not.
