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. But Abraham did not yet understand the promise. His mind at once turned to Ishmael, clinging to the belief that through him God’s gracious purposes were to be accomplished. In his affection for his son he exclaimed, “O that Ishmael might live before Thee!” Genesis 17:18. Again the promise was given, in words that could not be mistaken: “Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish My covenant with him.” Genesis 17:19. Yet God was not unmindful of the father’s prayer. “As for Ishmael,” He said, “I have heard thee: Behold, I have blessed him, ... and I will make him a great nation.” Genesis 17:20. (PP 146.1) MC VC

The birth of Isaac, bringing, after a lifelong waiting, the fulfillment of their dearest hopes, filled the tents of Abraham and Sarah with gladness. But to Hagar this event was the overthrow of her fondly cherished ambitions. Ishmael, now a youth, had been regarded by all in the encampment as the heir of Abraham’s wealth and the inheritor of the blessings promised to his descendants. Now he was suddenly set aside; and in their disappointment, mother and son hated the child of Sarah. The general rejoicing increased their jealousy, until Ishmael dared openly to mock the heir of God’s promise. 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; his love for Ishmael or Hagar ought not to stand in the way, for only thus could he restore harmony and happiness to his family. 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. The father’s heart was heavy with unspoken grief as he sent away Hagar and his son. (PP 146.2) MC VC

The instruction given to Abraham touching the sacredness of the marriage relation was to be a lesson for all ages. It declares that the rights and happiness of this relation are to be carefully guarded, even at a great sacrifice. Sarah was the only true wife of Abraham. Her rights as a wife and mother no other person was entitled to share. She reverenced her husband, and in this she is presented in the New Testament as a worthy example. But she was unwilling that Abraham’s affections should be given to another, and the Lord did not reprove her for requiring the banishment of her rival. Both Abraham and Sarah distrusted the power of God, and it was this error that led to the marriage with Hagar. (PP 147.1) MC VC

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. He had shown distrust of God in concealing the fact that Sarah was his wife, and again in his marriage with Hagar. 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. (PP 147.2) MC VC

At the time of receiving this command, Abraham had reached the age of a hundred and twenty years. He was regarded as an old man, even in his generation. In his earlier years he had been strong to endure hardship and to brave danger, but now the ardor of his youth had passed away. One in the vigor of manhood may with courage meet difficulties and afflictions that would cause his heart to fail later in life, when his feet are faltering toward the grave. But God had reserved His last, most trying test for Abraham until the burden of years was heavy upon him, and he longed for rest from anxiety and toil. (PP 147.3) 2 I MC VC

The patriarch was dwelling at Beersheba, surrounded by prosperity and honor. He was very rich, and was honored as a mighty prince by the rulers of the land. Thousands of sheep and cattle covered the plains that spread out beyond his encampment. On every side were the tents of his retainers, the home of hundreds of faithful servants. The son of promise had grown up to manhood by his side. Heaven seemed to have crowned with its blessing a life of sacrifice in patient endurance of hope deferred. (PP 147.4) MC VC
