I don't know why you would be unacceptable to God because you are a Jew. Sin makes us unacceptable to God, as I'm sure you are aware from the OT ritual requirements for purification. The problem is that both Jews and Gentiles are unacceptable to God, because all have sinned and fallen short of the glory of God. This isn't limited to a certain "race" of people, but all people born of Adam are in this predicament. God, however, has sent the second Adam, one greater than Moses, more wise than Solomon, a priest in the order of Melchizedek, and a sacrifice greater than all sacrifices, because it was offered up once and not year after year. People are accepted by God in His Son, Yeshua, the Christ, Jesus. If one wants God to accept them, they must receive His Son.
