Ethical Monotheists

This week in class, we learned a lot about the character of Yitzchak versus the character of Avraham. In short, they did the same things. The only difference was that Yitzchak had to mend and push the things his father did forward. Since this is the case, I was wondering if Yitzchak continued spreading ethical monotheism the way that Avraham had.

We learned that part of Avraham's main purpose and goal was to spread ethical monotheism and educate the people of the world about the one, true G-d. Yitzchak was very different. He was an ethical monotheist and grew up surrounded by Avraham and his ideals. Although Yitzchak did take after Avraham in many ways, he did not have the exact same personality or inclinations. Avraham was more outgoing and a "people person". Yitzchak was more of a reserved person and directed his energy towards improving the internal structure of ethical monotheism. The Torah never tells us that he went out of his way to seek followers. Now, the question is: did G-d change his expectations of his "chosen" people? I don't know the answer to that. All I do know is that Avraham accumulated followers. In the time of Yitzchak, they seem to have disappeared. One theory is that they learned what they could from Avraham and then moved off on their own. After that, they went on to make their own, obscure ethical monotheist religions. As of today, these religions did not turn into worldwide phenomena. (All three "ethical" monotheistic religions came from Avraham biologically.) As far as Yitzchak's role goes, I think that he and G-d decided that it would be better if the religion was contained to the immediate family of Avraham.

In the Torah, we never hear about Avraham's followers again. I have given you my interpretation and explanation of this event, but I would like to know if anyone else comes up with anything that makes more sense logically.
