When the kingdom was divided between Israel and Judah, Judah became the steward of the biblical faith in God. The northern kingdom of Israel went into idolatry and paganism. This is why the people who practiced the faith came to be known as “Jews,” and the faith itself became known as “Judaism.” A Jew was not merely a geographical designation meaning someone from the territory of Judah. It came to identify someone who practiced the faith preserved through Judah. This is the faith Yeshua was born into. And He did not come to abolish it and start something entirely new. He came to fulfill it, perfect it, and make it available to the whole world, through faith rather than works.
