“ ‘Behold, I am with you and will keep you wherever you go, and will bring you back to this land; for I will not leave you until I have done what I have spoken to you’ ” (Gen. 28:15, NKJV)
“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 blessing. 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. . . .
“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. 1 Peter 1:12.”1
