Are we still suppose to keep all Ten Commandments?

Do not be deceived and lulled into a strong delusional hypnotic sleep about lawlessness, the church in apostasy is a reality. Look around to see how values systems in our lifetimes have deteriorated. Majority Christian democratic countries has in our generation start to allow the killing of babies in the womb, what God calls an abomination, Christian leaders have come to condone, man and his created science is exulted above God and his creation, etc., etc....

1 John 3 (New King James Version)
4Whoever commits sin also commits lawlessness, and sin is lawlessness.

2 Thessalonians 2 (English Standard Version)
The Man of Lawlessness /
The Great Apostasy
1Now concerning the coming of our Lord Jesus Christ and our being gathered together to him, we ask you, brothers,a 2not to be quickly shaken in mind or alarmed, either by a spirit or a spoken word, or a letter seeming to be from us, to the effect that the day of the Lord has come. 3Let no one deceive you in any way. For that day will not come, unless the rebellion comes first, and the man of lawlessnessb is revealed, the son of destruction,c 4who opposes and exalts himself against every so-called god or object of worship, so that he takes his seat in the temple of God, proclaiming himself to be God. 5Do you not remember that when I was still with you I told you these things? 6And you know what is restraining him now so that he may be revealed in his time. 7For the mystery of lawlessness is already at work. Only he who now restrains it will do so until he is out of the way. 8And then the lawless one will be revealed, whom the Lord Jesus will kill with the breath of his mouth and bring to nothing by the appearance of his coming. 9The coming of the lawless one is by the activity of Satan with all power and false signs and wonders, 10and with all wicked deception for those who are perishing, because they refused to love the truth and so be saved. 11Therefore God sends them a strong delusion, so that they may believe what is false, 12in order that all may be condemned who did not believe the truth but had pleasure in unrighteousness.

Is he really new? Hard to tell anymore

Is one of God's Laws not being able to use the "O" in His Name?

Keeping all 613 mitzvot is impossible. You are a false teacher.

Now we know that whatever the law says, it says to those who are under the law,
so that every mouth may be silenced and the whole world held accountable to God.
Romans 3:19

But if you are led by the Spirit, you are not under the law. Galatians 5:18

Corban: "The Jew is still under this Law, but the Believer is not"

You say the Jew is still under the Law, but the Believer is not. What would you say about a Jewish Believer (being together with Gentile Ephraimites part of the commanded Israelites), to be under the Law or not? For instance the Sabbath being an eternal command (even until the return of Christ Yeshua to the earth following the great tribulation, and in the millennial Kingdom, Revelation 20, Ezekiel 37-48, after Christ Yeshua's return to earth) from God to be kept by Israelites (like Jews) throughout all their generations?

Leviticus 24 (New King James Version)
7And you shall put pure frankincense on each row, that it may be on the bread for a memorial, an offering made by fire to the Lord. 8Every Sabbath he shall set it in order before the Lord continually, being taken from the children of Israel by an everlasting covenant.

Matthew 24 (New King James Version)
20And pray that your flight may not be in winter or on the Sabbath. 21For then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be. 22And unless those days were shortened, no flesh would be saved; but for the [c]elect’s sake those days will be shortened. 29“Immediately after the tribulation of those days the sun will be darkened, and the moon will not give its light; the stars will fall from heaven, and the powers of the heavens will be shaken. 30Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. 31And He will send His angels with a great sound of a trumpet, and they will gather together His [d]elect from the four winds, from one end of heaven to the other.

Revelation 20 (New King James Version)
4And I saw thrones, and they sat on them, and judgment was committed to them. Then I saw the souls of those who had been beheaded for their witness to Jesus and for the word of God, who had not worshiped the beast or his image, and had not received his mark on their foreheads or on their hands. And they lived and reigned with Christ for [a]a thousand years.

In the millennium Kingdom, starting in Revelation 20, Sabbaths are kept, as described in Ezekiel 37-48:

Ezekiel 46 (New King James Version)
3Likewise the people of the land shall worship at the entrance to this gateway before the Lord on the Sabbaths and the New Moons.

Would you apply both 1 & 2's actions below as living in the spirit of the Law, or just 1 or 2, or none, and why?

1. Would keeping God's Sabbath, for instance, be loving God with all your heart, soul, strength and mind?
2. Would not murdering your neighbour, for instance, be loving your neighbour as thyself?

As impossible it is to keep the 613 mitzvot, just as impossible it is to love God with all your heart, mind, sole and strength, and your neighbour as yourself.

Jesus was the total fulfilment of the OT Law. We live in Christian Liberty now. We live according to the spirit of the Law, not the letter. The spirit of the Law is summed up in this...

Luke
10:27 And he answering said, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy strength, and with all thy mind; and thy neighbour as thyself.
10:28 And he said unto him, Thou hast answered right: this do, and thou shalt live.

Those laws (traditions of men) need to be distinguished from the Laws of God. My question is: The 600 plus laws mentioned by the more scholarly posters, are the laws made for certain circumstances among those? Are those laws meant for certain times and circumstances only part of the 600 plus laws? The laws Jesus condemned since they caused unnecessary burdens if not removed when no longer needed..

Those 613 laws were given under the old covenant, they use physical things that humans could understand to symbolize the spiritual.

Now the Lord communicates with us through the holy spirit, direct to our hearts that contain Christ. We are not to cut foreskin, physically, we are to belong to the lord in spirit and truth. We don't have to never mix fabric as a symbol of not mixing with those of false gods, we stay true to the Lord. And on and on.

The laws that caused unnecessary burdens that Jesus expected the lawyers to "lift a finger" to remove, are they among the 613?

It depends on if you are reading them through the old covenant, as the physical that is symbolic of the law, or you are reading them as we are to read them today--through the new covenant that is to read them in spirit and truth. The old covenant tells that to cut foreskin is important as a sign you belong to the Lord, the new covenant says belonging to the lord is not in the cutting of skin but in spirit and truth. We are to go by the new covenant, we are to obey the command to be circumcised, but not the commandment to cut foreskin.

We are to listen to the Lord, knowing all scripture is of the Lord.

Woah! There's nothing in the Ten Commandments about circumcision. But in the sermon on the mount if we can just love God with all of our hearts, minds and souls. + Love our neighbors as we love ourselves then we will be obedience to the Ten Commandments. It should be a no brainer.

Do not be deceived and lulled into a strong delusional hypnotic sleep about lawlessness, the church in apostasy is a reality. Look around to see how values systems in our lifetimes have deteriorated. Majority Christian democratic countries has in our generation start to allow the killing of babies in the womb, what God calls an abomination, Christian leaders have come to condone, man and his created science is exulted above God and his creation, etc., etc....

Salvation is always the same, there is no alternate route to God. Believers are then sealed with the Holy Spirit. I will say again, I have not ever come across anyone believing that you can still sin all you want. And I am well travelled.
