How should he slay the lad! Even if he could get the consent of his wounded and protesting heart, how could he reconcile the act with the promise, "In Isaac shall thy seed be called"? This was Abraham's trial by fire, and he did not fail in the crucible. While the stars still shone like sharp white points above the tent where the sleeping Isaac lay, and long before the gray dawn had begun to lighten the east, the old saint had made up his mind. He would offer his son as God had directed him to do, and _then trust God to raise him from the dead_. This, says the writer to the Hebrews, was the solution his aching heart found sometime in the dark night, and he rose "early in the morning" to carry out the plan. It is beautiful to see that, while he erred as to God's method, he had correctly sensed the secret of His great heart. And the solution accords well with the New Testament Scripture, "Whosoever will lose for my sake shall find." God let the suffering old man go through with it up to the point where He knew there would be no retreat, and then forbade him to lay a hand upon the boy. To the wondering patriarch He now says in effect, "It's all right, Abraham. I never intended that you should actually slay the lad. I only wanted to remove him from the temple of your heart that I might reign unchallenged there. I wanted to correct the perversion that existed in your love. Now you may have the boy, sound and well. Take him and go back to your tent. Now I know that thou fearest God, seeing that thou hast not withheld thy son, thine only son, from me." Then heaven opened and a voice was heard saying to him, "By myself have I sworn, saith the Lord, for because thou hast done this thing, and hast not withheld thy son, thine only son: that in blessing I will bless thee, and in multiplying I will multiply thy seed as the stars of the heaven, and as the sand which is upon the sea shore; and thy seed shall possess the gate of his enemies; and in thy seed shall all the nations of the earth be blessed; because thou hast obeyed my voice." 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.
