What is the definition of a Jew? we first get introduced to Avraham Avinu only when a Hashem gives him his first Commandment to leave his land. We don’t even bring up past 75 years of history, personal accomplishments and growth. Because the true definition of a Jew is not like other people who connect based on their own accomplishments and reasons, which definition is very limited because it’s based on human, but we connect by doing a mitzvah following and doing what Hashem wants connecting us to his essence.
