"The Law of the Lord is perfect, converting the soul..." (Psalm 19:7)
"Make Thy face to shine upon Thy servant; and teach me Thy statutes," (Psalm 119:35)
"As the Gemara puts it'...concerning the seven commandments they are thought of as 'sit and do nothing' (sheb ve'al ta'aseh),'" pg. 26, Novak, "The Image of the Non-Jew in Judaism"How can a sit-and-do-nothing approach transform man into a perfect being and bring him into contact with G-d?
There is no intimacy in the so-called Noahide laws, no revelation of G-d's love for His People, no command of love whatsoever, and the most glaring omission of all: no mention of the law of blood atonement (quite a faulty theological presupposition).
Now, this little test I've made is only useful for establishing the illegitimacy of false systems of law. But to know what is the legitimate source of law, please read the following post:
MESSIANIC GENTILE MANIFESTO
And, if you don't have time to read it, let me summarize: there is One-Law that G-d gave in Scripture for members of the covenant and that is the Sinaitic Torah. Yeshua did not abolish this Law but commanded that it be observed and that His disciples teach it all over the world.
