Avraham’s ultimate test of faith was Akeidas Yitzchak. The way we teach children, the challenge was to overcome his attachment to his son, even though this very same son was supposed to be heir to the covenant.
The Ran explains that there is a major subtlety into what was asked of Avraham. Hashem says: קַח-נָא אֶת-בִּנְךָ אֶת-יְחִידְךָ אֲשֶׁר-אָהַבְתָּ, אֶת-יִצְחָק, וְלֶךְ-לְךָ, אֶל-אֶרֶץ הַמֹּרִיָּה; וְהַעֲלֵהוּ שָׁם, לְעֹלָה – Please take your son, your only son, whom you love, Yitzchak, and go, for yourself, to the land of Moriah, and sacrifice him, as a burnt offering. (22:2).
The Ran points out that Hashem said קַח-נָא – “please take”. This was a request. It was not an instruction. It is quite possible that if Avraham had refused, he would not have violated Hashem word, as Hashem did not require it, and Avraham did not “need” to go through with it. It remained Avraham’s choice.
The Slonimer Rebbe adds a further dimension to the turmoil he faced. As Avraham approached the mountain:
וַיִּשָּׂא אַבְרָהָם אֶת-עֵינָיו וַיַּרְא אֶת-הַמָּקוֹם–מֵרָחֹק – Avraham lifted his eyes, and saw הַמָּקוֹם from a distance. (22:4)
Classically, this means that he literally “saw the place”. But הַמָּקוֹם is also a name of Hashem – He is “The Place”, He is everywhere, the Omnipresent.
In this context, וַיִּשָּׂא אַבְרָהָם אֶת-עֵינָיו וַיַּרְא אֶת-הַמָּקוֹם–מֵרָחֹק means that Avraham looked at the situation he was in, what he was about to do, and felt a distance between himself and Hashem. Avraham was doing what Hashem had requested, but he knew that what he was doing did not feel right. It tore him apart – he’d spent his entire life up to that point fighting human sacrifice, and yet here he was, about to sacrifice his son, throwing away his entire future. וַיַּרְא אֶת-הַמָּקוֹם–מֵרָחֹק – Avraham felt a distance between himself and Hashem.
At the crescendo, the Torah records that וַיִּשְׁלַח אַבְרָהָם אֶת-יָדוֹ, וַיִּקַּח אֶת-הַמַּאֲכֶלֶת, לִשְׁחֹט, אֶת-בְּנוֹ – Avraham sent his hand, and picked up the blade, to slaughter his son. The Torah doesn’t say that “He picked up the knife,”; but that he “sent his hand”. There is a disembodiment, dissociating his hands action from him. He could not believe what he was forcing himself to do!
We read this on Rosh Hashana, and apart from the obvious merit the story recalls, perhaps we can relate to this on a personal level. Things aren’t always clear cut what the right thing to do is. We don’t always “feel it”. Even the greatest of us was torn once.
