The story about Abraham sacrificing Isaac: Gen 21:12
But God said to him, “Do not be so distressed about the boy and your slave woman. Listen to whatever Sarah tells you, because it is through Isaac that your offspring will be reckoned.
and later: Gen 22:2
Then God said, “Take your son, your only son, whom you love—Isaac—and go to the region of Moriah. Sacrifice him there as a burnt offering on a mountain I will show you.”
Abraham used to dispute with God previously (Gen 18:23). If he listened, shouldn't he answer something like "And what about his offsprings, huh?"
Couldn't be the point something like Do you remember what I told you? It is hard to believe that the message is Be fanatic. The Gen 22:12 could be a polite way how to say Stop it, fool!
I'd like to know if there is some inconsistency in this explanation and consequently: if Abraham passed or fail his test.
