Because the infant has no choice but to depend on its parents, there is no point in saying the infant trusts them. Indeed, it is not sensible to say that Abraham trusts his god, given his beliefs. He might have failed to follow that god’s orders because of weakness of will, or he might have revised his view of the goodness of his god and the rightness of following his orders. If Abraham could not revise his beliefs, however, then there would be no question of choice for him of whether to sacrifice Isaac, any more than if his son had been taken from him by disease.

DEFINE: Clarifies that genuine trust implies choice — if beliefs can't be revised, there is no question of trusting, only of compulsion or dependence.
