Jews are supposed to find that repugnant, the whole point is that G-d stops the execution because it is wrong, he's demanding Abraham think for himself. Because Abraham failed the test, G-d stopped speaking to him (G-d spoke to Abraham several times before the attempted sacrifice, but never afterwards).
Wow. I've never heard that explanation of Gen. 22 before: that Abraham failed. Why do you think so in view of what God says at the end of the chapter:
22:12 And he said, Lay not thy hand upon the lad, neither do thou anything unto him. For now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son, from me.
22:13 And Abraham lifted up his eyes, and looked, and behold, behind [him] a ram caught in the thicket by his horns. And Abraham went and took the ram, and offered him up for a burnt-offering in the stead of his son.
22:14 And Abraham called the name of that place Jehovah- jireh. As it is said to this day, In the mount of Jehovah it shall be provided.
22:15 And the angel of Jehovah called unto Abraham a second time out of heaven,
22:16 and said, By myself have I sworn, saith Jehovah, because thou hast done this thing, and hast not withheld thy son, thine only son,
22:17 that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heavens, and as the sand which is upon the seashore. And thy seed shall possess the gate of his enemies.
22:18 And in thy seed shall all the nations of the earth be blessed. Because thou hast obeyed my voice.
God blesses Abraham more intensely than ever before. Verse 17 promises national greatness and dominence of his children and verse 18 promises that the Messiah would come from Abraham's children. So, why don't you think God was pleased with Abraham?
