"Isaiah, whose prophetic office was honored by the personal testimony of Christ and the apostles, manifested in numerous passages the burden of his conviction relating to the great event of the Savior’s advent and ministry on earth. With the forcefulness of direct revelation he told of the Virgin’s divine maternity, whereof Immanuel should be born, and his prediction was reiterated by the angel of the Lord, over seven centuries later. Looking down through the ages the prophet saw the accomplishment of the divine purposes as if already achieved, and sang in triumph: ’For unto us a child is born, unto us a son is given: and the government shall be upon his shoulder: and his name shall be called Wonderful, Counselor, The mighty God, The everlasting Father, The Prince of Peace. Of the increase of his government and peace there shall be no end, upon the throne of David, and upon his kingdom, to order it, and to establish it with judgment and with justice from henceforth even forever.’
"Immediately prior to its fulfillment, the blessed promise was repeated by Gabriel, sent from the presence of God to the Chosen Virgin of Nazareth.

“Isaiah was permitted to read the scroll of futurity as to many distinguishing conditions to attend the Messiah’s lowly life and atoning death.

The Lord’s dying with sinners, and His burial in the tomb of the wealthy were likewise declared with prophetic certainty.” (Jesus the Christ, pp. 46-7)

“From those ancient inspired men we learn the fact, that, not only a Son was to be sent; but that that Son was to be no less than an everlasting Father, a mighty God, a Prince of peace! that from Bethlehem this illustrious personage was to come forth, and when he should come forth, was to be lead as a sheep to the slaughter, be numbered with transgressors, bear the sins of many, and be smitten for the children of men; but suffer this affliction to make intercession for the transgressors.” (Messenger and Advocate, vol 2, p. 270)
