When Abraham was nearly one hundred years old, the promise of a son was repeated to him, with the assurance that the future heir should be the child of Sarah.... The birth of Isaac, bringing, after a life-long waiting, the fulfillment of their dearest hopes, filled the tents of Abraham and Sarah with gladness.... TA 77.2
Sarah saw in Ishmael's turbulent disposition a perpetual source of discord, and she appealed to Abraham, urging that Hagar and Ishmael be sent away from the encampment. The patriarch was thrown into great distress. How could he banish Ishmael his son, still dearly beloved? In his perplexity he pleaded for divine guidance. The Lord, through a holy angel, directed him to grant Sarah's desire.... And the angel gave him the consoling promise that though separated from his father's home, Ishmael should not be forsaken by God; his life should be preserved, and he should become the father of a great nation. Abraham obeyed the angel's word, but it was not without keen suffering.—Patriarchs and Prophets, 146, 147. TA 77.3
God had called Abraham to be the father of the faithful, and his life was to stand as an example of faith to succeeding generations. But his faith had not been perfect.... That he might reach the highest standard, God subjected him to another test, the closest which man was ever called to endure. In a vision of the night he was directed to repair to the land of Moriah, and there offer up his son as a burnt offering upon a mountain that should be shown him.... TA 78.1
The command was expressed in words that must have wrung with anguish that father's heart: “Take now thy son, thine only son Isaac, whom thou lovest, ... and offer him for a burnt offering.” Isaac was the light of his home, the solace of his old age, above all else the inheritor of the promised blessing.... TA 78.2
Satan was at hand to suggest that he must be deceived, for the divine law commands, “Thou shalt not kill,” and God would not require what He had once forbidden. Going outside his tent, Abraham looked up to the calm brightness of the unclouded heavens, and recalled the promise made nearly fifty years before, that his seed should be innumerable as the stars. If this promise was to be fulfilled through Isaac, how could he be put to death? Abraham was tempted to believe that he might be under a delusion.... He remembered the angels sent to reveal to him God's purpose to destroy Sodom, and who bore to him the promise of this same son Isaac, and he went to the place where he had several times met the heavenly messengers, hoping to meet them again, and receive some further direction; but none came to his relief.—Patriarchs and Prophets, 147, 148. TA 78.3
All day he had hopes of meeting an angel coming to bless and comfort him, or perhaps to revoke the command of God, but no messenger of mercy appeared.... The second long day comes to a close, another sleepless night is spent in humiliation and prayer, and the journey of the third day is commenced.—The Signs of the Times, April 1, 1875. TA 79.1
At the appointed place they built the altar and laid the wood upon it. Then with trembling voice, Abraham unfolded to his son the divine message. It was with terror and amazement that Isaac learned his fate, but he offered no resistance.... He was a sharer in being called to give his life as an offering to God.... TA 79.2
And now the last words of love are spoken, the last tears are shed, the last embrace is given. The father lifts the knife to slay his son, when suddenly his arm is stayed. An angel of God calls to the patriarch out of heaven, “Abraham, Abraham!” He quickly answers, “Here am I.” And again the voice is heard, “Lay not thine hand upon the lad, neither do thou anything unto him; for now I know that thou fearest God, seeing thou has not withheld thy son, thine only son, from me.” ... TA 79.3
God gave His Son to a death of agony and shame. The angels who witnessed the humiliation and soul anguish of the Son of God were not permitted to interpose, as in the case of Isaac. There was no voice to cry, “It is enough.” To save the fallen race, the King of glory yielded up His life.... TA 79.4
Heavenly beings were witnesses of the scene as the faith of Abraham and the submission of Isaac were tested.... All heaven beheld with wonder and admiration Abraham's unfaltering obedience. All heaven applauded his fidelity. Satan's accusations were shown to be false.... TA 80.1
It had been difficult even for the angels to grasp the mystery of redemption—to comprehend that the Commander of heaven, the Son of God, must die for guilty man. When the command was given to Abraham to offer up his son, the interest of all heavenly beings was enlisted. With intense earnestness they watched each step in the fulfillment of this command. When to Isaac's question, “Where is the lamb for a burnt offering?” Abraham made answer, “God will provide himself a lamb”: and when the father's hand was stayed as he was about to slay his son, and the ram which God had provided was offered in the place of Isaac—then light was shed upon the mystery of redemption, and even the angels understood more clearly the wonderful provision that God had made for man's salvation.—Patriarchs and Prophets, 152, 154, 155.
