Pizza, full Torah Observance is only possible in the days of Messiah. Spoon, I'm uncertain as to what your question means. If you are asking 'Why are you a Jew', well, because I am. If you mean, why am I an Observant Jew when my family isn't & I wasn't raised as such, the answer is multi-faceted. But, in simplest terms, I am a Jew because God has called me to serve Him in that unique way. He has never abandoned His People Israel, & I believe it is my duty to uphold my end of the Covenant, as He has upheld His.
