Obviously, you did not understand what it is to be a Christian.
For had you properly understood it, you would not have converted to Judaism.
Romans 10:4 For Christ is the end of the law for righteousness to every one that believeth.
And now as "a Jew" you are just as clueless about what it means to be "a Jew."
For the following clearly states that "a Jew" is supposed to be basing his assertions on Scripture.
Romans 2:17 Behold, thou art called a Jew, and restest in the law, and makest thy boast of God, 2:18 And knowest his will, and approvest the things that are more excellent, being instructed out of the law; 2:19 And art confident that thou thyself art a guide of the blind, a light of them which are in darkness, 2:20 An instructor of the foolish, a teacher of babes, which hast the form of knowledge and of the truth in the law.
Isaiah 8:20.
