Avraham earned many rewards for passing his tests. Rashi writes, "Avraham was tested ten times corresponding to the ten mamaros [that Hashem said] to create the world. It is in Avraham's merit that the world stands. Corresponding to Avraham Avinu's ten tests, of which he passed, Hakadosh Baruch Hu brought ten miracles in Mitzrayim and ten at the Yam Suf. Also, Hashem brought ten makos on the Mitzriyim, and ten at the Yam Suf. And, corresponding to these ten tests, Hashem gave Avraham's offspring the Ten Commandments. And when the luchos, which had the Ten Commandments written on them, were broken, the merit of Avraham’s belief in Hashem and passing ten tests protected the Jewish nation from destruction..."
Avraham and his descendants earned and gained many other blessings and marvelous benefits because he passed these ten tests. By the Akeidah, the word מאכלת is used for a knife. Rashi (22:6) writes, "It is called מאכלת because Bnei Yisrael אוכלין, eat, the reward [of this test]."
As we wrote above, the Mishnah states (Avos 5:3), השלום עליו אבינו אברהם נתנסה נסיונות עשרה בכלם ועמד, "Avraham Avinu was tested ten times and he passed all ten tests." In this Mishnah, Avraham is called אבינו אברהם, "Avraham, our father." Tosfos Yom Tov zt'l explains that this is because each test that Avraham passed brought many blessings and salvations for his descendants.
Rav Pinchos Koritzer zt'l said: “Until parashas Lech Lecha, the world was unhappy and confused. Afterwards, the chesed of Avraham is aroused, bringing salvation unto the world.”
