Genesis 22
Now it came to pass after these things that God tested Abraham, and said to him, “Abraham!”
11 And an angel of the Lord called him out of heaven, and said, Abraam, Abraam. And he said, Behold, I am here. 12 And he said, Lay not thine hand upon the child, neither do anything to him, for now I know that thou fearest God, and for my sake thou hast not spared thy beloved son.
God's prophet (likely Moses) says one thing, you say something else. Like all doctrines and religions, they fall apart in the face of the Holy Bible.
