Unless you are a Karaite, it is you that have abandoned Torah.
I’m not a Karaite.I’m not even Jewish. I am a Noahide.
I will explain more about the Noahide faith if you would like. Most people have not heard of the Noahide faith.
In short,Noahides accept the Torah as the only word of G-d,Just like the Jews.
I have not abandoned Torah at all. But any Jew who accepts Jesus as his or her Lord and savior has.
