Isaiah 53:10-11

10, 11. It pleased the Lord to bruise him Notwithstanding his innocence. His bruising thus accords with the divine idea of permitting (Acts 2:23) an expression of love through suffering, which expression Messiah alone is competent to make. The time of being pleased with Old Testament sacrifices is proleptically past, as brought out in Psalms 40:6-8, (Lo, I come, etc.) But the time of receiving reward for suffering is now at hand.

He shall see his seed Love declared to the world through a suffering self-offering, is to reap fruit in a long line of spiritual children whose own deserved penal sufferings are offset by Messiah’s free suffering instead.

He shall prolong his days This he is to do in the great mediatorial aion the period of the great Christian dispensation that is to follow during which his joy shall abound more and more through the vast increase of redeemed ones coming into his kingdom. A fitting and satisfying reward shall this prove to be. The same idea is expanded in Isaiah 53:11.

By his knowledge His “knowledge,” probably, of the eternal plan to save men; “knowledge” of the how, and why, and extent, of such a plan, possibly not fully contemplated till his glorification began, just prior to his priestly sufferings, and continuing to his exaltation. See Matthew 24:36. Such knowledge was relief to those sufferings. He saw from the cross “the glory that should follow,” and in a sense was thereby sustained. In such case he could freely and joyfully interpose for a world of sinners with sufferings due only to them, and of such a character that divine justice and government might accept his suffering in lieu of theirs, and be in no jeopardy.
