The old man of God lifted his head to respond to the Voice, and stood there on the mount strong and pure and grand, a man marked out by the Lord for special treatment, a friend and favorite of the Most High. Now he was a man wholly surrendered, a man utterly obedient, a man who possessed nothing. He had concentrated his all in the person of his dear son, and God had taken it from him. God could have begun out on the margin of Abraham’s life and worked inward to the center; He chose rather to cut quickly to the heart and have it over in one sharp act of separation. In dealing thus He practiced an economy of means and time. It hurt cruelly, but it was effective.
