Genesis 22:1-18 and Qur'an 37:99-113 Abraham was tested by God and told to murder his own son. He obeyed, although God stopped him at the last moment, and gave him incredible rewards for his loyalty. Yet Abraham clearly failed any possible moral test: in going to murder his own son for God, he was displaying the worst signs of religion: insanity, murderous willingness to attempt spiritual gain at any cost, and an inability to question the true worth of his own beliefs. He followed criminal orders without asking why - a trend that in history has had terrible consequences yet is endorsed in the Bible. Not only that, he did not even question the highly likely probability that hearing voices is not a good thing.
In Deut. 12:30-31 God specifically says that human sacrifice is an abomination for god, which "he hateth", and Jer. 19:4-6 says God does not command human sacrifice, so Abraham also failed to know God very well when he decided that murdering his son was the right thing to. The Bible is obviously full of contradictions: Abraham, revered and holy, is rewarded by God for mindlessly obeying an order to kill his son; an order which goes against the Bible itself. God, later on, goes on to sacrifice its own son. It was said to be a test, a trial, to see if Abraham was loyal. But to say that God needed to do a test contradicts the all-knowing nature of God. Therefore, this story is immoral, makes no sense, and contradicts scripture in multiple ways: It cannot be true or divinely inspired, and it does not deserve the attention of good people or believers in a good god.
