Kierkegaard on Father Abraham

I found the following quote from Soren Kierkegaard in the introduction of the book Provocations: Spiritual Writings of Kierkegaard, which, as the title indicates, is a collection of his writings:

"To illustrate the difference between the ethical and religious spheres, Kierkegaard cites Abraham, the "father of all those who believe." Abraham, a righteous man, is the paragon of faith because instead of heeding the moral law--"Thou shall not kill" -- he heeded God's command to sacrifice Isaac. Abraham acted as a true individual because his relationship to God, not to the moral law, was primarey in his life. He did not meerly percieve God through morality or reduce God to the moral law. As a man of faith, Abraham subjected everything, including his ethical actions, to God. he was willing to sacrifice Isaac for the sake of his own relationship to God. He acted because God commanded him to act. He stood before God, answering to no one but God."
