Jesus continued, drawing a sharp contrast between the position of the Jews and that of Abraham: “Your father Abraham rejoiced to see My day: and he saw it, and was glad.”
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…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…
Through his own suffering, Abraham was enabled to behold the Saviour's mission of sacrifice. But Israel would not understand that which was so unwelcome to their proud hearts. Christ's words concerning Abraham conveyed to His hearers no deep significance. The Pharisees saw in them only fresh ground for caviling. They retorted with a sneer, as if they would prove Jesus to be a madman, “Thou art not yet fifty years old, and hast Thou seen Abraham?”
With solemn dignity Jesus answered, “Verily, verily, I say unto you, Before Abraham was, I AM.”
Silence fell upon the vast assembly. The name of God, given to Moses to express the idea of the eternal presence, had been claimed as His own by this Galilean Rabbi. He had announced Himself to be the self-existent One, He who had been promised to Israel, “whose goings forth have been from of old, from the days of eternity.” Micah 5:2, margin.
Again the priests and rabbis cried out against Jesus as a blasphemer. His claim to be one with God had before stirred them to take His life, and a few months later they plainly declared, “For a good work we stone Thee not; but for blasphemy; and because that Thou, being a man, makest Thyself God.” John 10:33. Because He was, and avowed Himself to be, the Son of God, they were bent on destroying Him. Now many of the people, siding with the priests and rabbis, took up stones to cast at Him. “But Jesus hid Himself, and went out of the temple, going through the midst of them, and so passed by.”
The Light was shining in darkness; but “the darkness apprehended it not.” John 1:5, R.V. DA 468-470
