Paul wrote to the Galatians, "I marvel that you are soon removed from him that called you into the grace of Christ unto another Gospel: which is not another; but there be some that trouble you, and would pervert the Gospel of Christ. But though we or an angel from heaven, preach any other Gospel unto you than what we have preached unto you, let him be accursed. As we said before, so say I now again, If any man preach any other Gospel unto you than what you have received, let him be accursed, Galatians 1:6-9.
There is only one Gospel that justifies the ungodly, Romans 4:5 and reconciles us and the world unto God, 2 Corinthians 5:18-19.
Paul said, "For by grace (God's goodness) are you saved through faith; and not that of yourselves: it is the gift of God: Not of works, lest any man should boast" Ephesians 2:8-9.
In Ephesians 2:8-9, Paul eliminated works as a means of salvation. The reason that salvation is not by works is because it is the gift of God. A gift cannot be earned or deserved otherwise it is not a gift. Some will say that the word "Grace" in this scripture means the grace of Christ. The word grace in this scripture means the grace of God. God was gracious in that he sent his Son to be the savior of the world, John 3:17.
Paul said, "Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law is the knowledge of sin" Romans 3:20.
Paul makes it clear that salvation is not by works, nor is it by obedience to the law. If it is not by works or obedience to the law, then it can only be by faith and by faith alone.
We do not serve God in the old way of the written code but in the new way of the Spirit. And our righteousness is credited by faith in Christ Jesus not by our own works.
However, the command of love exists by Christs command and those who love fulfill whatever commandment there is for love does no harm to a neighbor.
Jesus said unto him, “Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbor as thyself. On these two commandments hang all the law and the prophets”
Let no debt remain outstanding, except the continuing debt to love one another, for whoever loves others has fulfilled the law. 9 The commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not covet,” and whatever other command there may be, are summed up in this one command:
“Love your neighbor as yourself.”10 Love does no harm to a neighbor. Therefore love is the fulfillment of the law.
Jesus=>Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me.
A certain ruler asked him, “Good teacher, what must I do to inherit eternal life?”
19“Why do you call me good?” Jesus answered. “No one is good—except God alone.
20You know the commandments: ‘You shall not commit adultery, you shall not murder, you shall not steal, you shall not give false testimony, honor your father and mother.’
So, there is a difference in the ceremonial law vs the moral law. The moral law has not been abolished. The ceremonial law was a shadow of things to come.
And the body of Christ from peoples of all nations is not a physical nation nor a theocracy of Israel which was disbanded.
It is clear we are not free to sin.
The Moral law of God would be fulfilled as Paul and Jesus stated by Loving others as yourself.
Lawlessness, crime, immorality are addressed in the Moral law of God which states Gods character. (Love)
