Hebrews 11:17 By faith Abraham, when he was tried, offered up Isaac: and he that had received the promises offered up his only begotten son, 18 Of whom it was said, That in Isaac shall thy seed be called: 19 Accounting that God was able to raise him up, even from the dead; from whence also he received him in a figure.
[Patriarchs And Prophets pp. 154>155] The sacrifice required of Abraham was not alone for his own good, nor solely for the benefit of succeeding generations; but it was also for the instruction of the sinless intelligences of heaven and of other worlds. The field of the controversy between Christ and Satan—the field on which the plan of redemption is wrought out—is the lesson book of the universe. Because Abraham had shown a lack of faith in God's promises, Satan had accused him before the angels and before God of having failed to comply with the conditions of the covenant, and as unworthy of its blessings. God desired to prove the loyalty of His servant before all heaven, to demonstrate that nothing less than perfect obedience can be accepted, and to open more fully before them the plan of salvation.
Heavenly beings were witnesses of the scene as the faith of Abraham and the submission of Isaac were tested. The trial was far more severe than that which had been brought upon Adam. Compliance with the prohibition laid upon our first parents involved no suffering, but the command to Abraham demanded the most agonizing sacrifice. All heaven beheld with wonder and admiration Abraham's unfaltering obedience. All heaven applauded his fidelity. Satan's accusations were shown to be false. God declared to His servant, “Now I know that thou fearest God [notwithstanding Satan's charges], seeing thou hast not withheld thy son, thine only son from Me.” God's covenant, confirmed to Abraham by an oath before the intelligences of other worlds, testified that obedience will be rewarded.
It had been difficult even for the angels to grasp the mystery of redemption—to comprehend that the Commander of heaven, the Son of God, must die for guilty man. When the command was given to Abraham to offer up his son, the interest of all heavenly beings was enlisted. With intense earnestness they watched each step in the fulfillment of this command. When to Isaac's question, “Where is the lamb for a burnt offering?” Abraham made answer, “God will provide Himself a lamb;” and when the father's hand was stayed as he was about to slay his son, and the ram which God had provided was offered in the place of Isaac—then light was shed upon the mystery of redemption, and even the angels understood more clearly the wonderful provision that God had made for man's salvation.
Isaiah 53:5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. 6 All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all.
May God add His blessing to the study of His word. "Good night" and God bless!
