And Abraham is praised rather than condemned for being willing to kill his son.
No, he is praised for trusting the will of God, no matter how inscrutable it may seem. This is the same problem for atheists … that they cannot put themselves completely in the hands of God, no matter how unfathomable He may appear.
Angels are messengers of God, they do what God wills them to do.
You need to look at the outcome of the story of Abraham, the theme, instead of keying in on what you would like it to say because it plays into your agenda.
If God had really meant for Abraham to kill his son, he would not have been satisfied until Isaac was killed. And Jews and Catholics would not even exist today except in terror of being killed by their fathers.
O.K.?.
