My mind goes back to faithful Abraham, who, in obedience to the divine command given him in a night vision at Beersheba, pursues his journey with Isaac by his side. He sees before him the mountain which God had told him He would signalize as the one upon which he was to sacrifice. He removes the wood from the shoulder of his servant and lays it upon Isaac, the one to be offered. He girds up his soul with firmness and agonizing sternness, ready for the work which God requires him to do. With a breaking heart and unnerved hand, he takes the fire, while Isaac inquires: Father, here is the fire and the wood; but where is the offering? But, oh, Abraham cannot tell him now! 1TT 352.2
Father and son build the altar, and the terrible moment comes for Abraham to make known to Isaac that which has agonized his soul all that long journey, that Isaac himself is the victim. Isaac is not a lad; he is a full-grown young man. He could have refused to submit to his father's design had he chosen to do so. He does not accuse his father of insanity, nor does he even seek to change his purpose. He submits. He believes in the love of his father and that he would not make this terrible sacrifice of his only son if God had not bidden him do so. Isaac is bound by the trembling, loving hands of his pitying father because God has said it. The son submits to the sacrifice because he believes in the integrity of his father. But when everything is ready, when the faith of the father and the submission of the son are fully tested, the angel of God stays the uplifted hand of Abraham that is about to slay his son and tells him that it is enough. “Now I know that thou fearest God, seeing thou hast not withheld thy son, thine only son from Me.” Genesis 22:12. 1TT 352.3
This act of faith in Abraham is recorded for our benefit. It teaches us the great lesson of confidence in the requirements of God, however close and cutting they may be; and it teaches children perfect submission to their parents and to God. By Abraham's obedience we are taught that nothing is too precious for us to give to God. 1TT 353.1
