And as Paul clearly stated in Romans:
Not hearers of the law will be justified, but doers of the law.
Or as he put it in Hebrews 4:
[1] Let us therefore fear, lest, a promise being left us of entering into his rest, any of you should seem to come short of it..
[2] For unto us was the gospel preached, as well as unto them: but the word preached did not profit them, not being mixed with faith in them that heard it.
Obviously what Moses preached was the gospel that the apostles preached.
What could that have been?
I didn't think you knew what the Law of Liberty is...There is no liberty in the Torah...Liberty is freedom...The Torah is bondage...
Christians have become free of the bondage of the Torah...
Gal 3:23 But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed.
Before faith came we are were justified by the law (works)(Rom; 2:13)...
But now, after faith came:
Rom 3:20 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.
Rom 3:21 But now the righteousness of God without the law is manifested, being witnessed by the law and the prophets;
Rom 3:22 Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:
Gal 3:24 Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.
Gal 3:25 But after that faith is come, we are no longer under a schoolmaster.
Rom 3:28 Therefore we conclude that a man is justified by faith without the deeds of the law.
This stuff is pretty easy to find in the scriptures but I guess the hard part is believing it, ain't it???
We learned from the law to know to how to please God (ie. love God, love your neighbor) but we are not under its bondage...
Now, what about the law of liberty???
Gal_5:1 Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
We can wear shorts to church and eat a ham sandwich afterward and then go work on the loud muffler on the car...Every day of the week...That is the law of liberty...
And as James says, if we combine that liberty with good works for (not us) God, we will receive blessings...
Jas_1:25 But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
THIS, the Torah is NOT the law of liberty:
Jas 2:10 For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all.
