True that every Christian would already keep the laws that are called “Noahide” , but not as a “Ben Noach”. nor as an attempt at Righteousness conferred upon Gentiles by Rabbis. Christians would keep them be cause they are for the most part s scriptural and even re-iterated in the NT. Our Righteousness is given us as a gift, by Messiah, of whom it is written, “By His knowledge shall my Righteous servant justify the many”. As for being a loser, you are right. I am a loser, I am a sinner and have failed God, but have found Hesed, grace, through the Righteousness of His Son. I do not denounce “another religion” i call upon those who practice that religion to be consistent with it, and accept Messiah and the New Covenant which Jeremiah promised. “My people have committed two evils, they have forsaken me the fountain of Living waters, and hewn out cisterns for themselves, which can hold no water”. Such is Rabbinism, a false religion that Moses, Ezekiel or Jeremiah would never recognize.
