Why didn't he??

Scripture provides normative precedent for speaking one’s mind directly to God, even challenging God over the injustice or wrongness of any situation in one’s own life or in the wider world.

This biblical precedent of vigorous prayer raises the question of why Abraham didn’t intercede for Isaac. Given this weighty precedent, we might wonder why he didn’t cry out like the psalmist in Psalm 22, “My God, my God, why have you forsaken me?” Or he could have pleaded, as Jesus did in Gethsemane, “Remove this cup from me.”

Indeed, just four chapters before the Aqedah, Abraham does challenge God, with great boldness.—Abraham's Silence, 132–33
