Your father Abraham rejoiced to see My day: and he saw it, and was glad. John 8:56.
Abraham had greatly desired to see the promised Saviour. He offered up the most earnest prayer that before his death he might behold the Messiah. And he saw Christ. A supernatural light was given him, and he acknowledged Christ’s divine character. He saw His day, and was glad. He was given a view of the divine sacrifice for sin. Of this sacrifice he had an illustration in his own experience. The command came to him, “Take now thy son, thine only son Isaac, whom thou lovest, ... and offer him ... for a burnt-offering.” Upon the altar of sacrifice he laid the son of promise, the son in whom his hopes were centered. Then as he waited beside the altar with knife upraised to obey God, he heard a voice from heaven saying, “Lay not thine hand upon the lad, neither do thou anything unto him; for now I know that thou fearest God, seeing that thou hast not withheld thy son, thine only son, from Me.” This terrible ordeal was imposed upon Abraham that he might see the day of Christ, and realize the great love of God for the world, so great that to raise it from its degradation, He gave His only begotten Son to a most shameful death.
Abraham learned of God the greatest lesson ever given to mortal. His prayer that he might see Christ before he should die was answered. He saw Christ; he saw all that mortal can see, and live. By making an entire surrender, he was able to understand the vision of Christ, which had been given him. He was shown that in giving His only begotten Son to save sinners from eternal ruin, God was making a greater and more wonderful sacrifice than ever man could make.—The Desire of Ages, 468, 469.
