BY LAUGHING AT THE STUPIDITY OF SIN
Hashem is of course the best M'chanech, and He chose making jokes out of Mitzrayim and their Treife lifestyle in order to give the best and most effective Mussar Shmuess and to help us overcome our Yetzer Hara in a happy way with our laughing at the stupidity of sin. Not always do people know how to be M'chanech others properly.
The Gemara warns a Rebbe: לְעולָם תְהֵא שְמֹאל דוחָה וְיָמִין מְקָרֶבֶת You are M'karev (bring close) strongly, with your right (dominant) hand, and if you need to reprimand, do it lightly, like a weak left hand. And not like Elisha HaNavi who pushed away his Talmid, Geichazi with two hands! There was no Tzaddik like Elisha HaNavi, who cried bitterly when he realized the cruelties the Melech Aram would eventually do to Klal Yisroel.
He didn’t talk to women, and the Shunamis said: קָדוש הוּא (הוּא קָדוש, וּמְשָרְתו אֵינו קָדוש ברכות י ב) he is a holy man. He performed double the Nissim of his Rebbe, Eliyahu HaNavi, and he was M'kadesh Shem Shamayim many times. He left his beloved family in order to be with Eliyahu HaNavi. He destroyed the household of Achav, and he was the true: מְשַמֵש assistant of Eliyahu HaNavi וְגְדולָה שִמושָהּ מִלִמודָהּ) and assisting your Rebbe is greater than just learning from him. (Gemara).
