Jewish History: Biblical History: Abraham not Protesting the Akedah:
Why didn't Abraham protest when he was told to sacrifice Isaac, when he did protest about the destruction of possible righteous people in Sodom?
1) For a (relatively) disinterested person to protest against possible injustice is one thing; to disobey or protest a direct Divine order
is quite another thing.
2) In the Talmud Yerushalmi (Taanis 2:4) and in many Midrashim,
Abraham is quoted as saying to G-d (afterwards) that he could have
protested when he was told to offer Isaac as a sacrifice, since
G-d had promised him descendants through Isaac, but he suppressed
his feelings and didn't protest.
3) Many commentators and Midrashim point out that G-d didn't
explicitly tell Abraham to sacrifice Isaac, but only to "raise
him up" as an offering. True, Abraham brought wood, fire, and
a knife to the mountain, but he may have believed that G-d
would provide an animal to be sacrificed; indeed, this is
what he told Isaac on the way up the mountain, and this is
what actually happened.
