R' Miller on Avraham and Sarah

Rabbi Avigdor Miller, Tape 412, True Modesty, 1:10:25 

Question: We see in the case of Rabbi Akiva that a woman can affect the man. How is the reverse and to what extent?  

Is the question can a man affect a woman? Certainly. Certainly. What do you think made Sarah great? Here Sarah became a great naviah. כֹּל אֲשֶׁר תֹּאמַר אֵלֶיךָ שָׂרָה, שְׁמַע בְּקֹלָה Avraham was told listen to Sarah. And Avraham is called a tefel b'navuah to Sarah.  That doesn't mean Avraham was less. Avraham was a bigger navi. Only Avraham was always in the street arguing with people. And when you argue you get excited so the schinah is not always able to rest on you. Sarah was magayeres es hanashim in her own home . So Sarah lived a tranquil life and therefore the navuah could come upon her more frequently.  But Sarah was the result of Avraham's tutelage. Avraham was her rebbe, no question.
