"153.4 Through type and promise God “preached before the gospel unto Abraham.” Galatians 3:8 . And the patriarch's faith was fixed upon the Redeemer to come. Said Christ to the Jews. “Your father Abraham rejoiced that he should see My day; and he saw it, and was glad.” John 8:56 , R.V., margin. The ram offered in the place of Isaac represented the Son of God, who was to be sacrificed in our stead. When man was doomed to death by transgression of the law of God, the Father, looking upon His Son, said to the sinner, “Live: I have found a ransom.” PP 154.1"
"And the scripture, foreseeing that God would justify the heathen through faith, preached before the gospel unto Abraham, saying, In thee shall all nations be blessed."
Ellen White directly references Galatians 3:8 in this passage.
"Your father Abraham rejoiced to see my day: and he saw it, and was glad."
Ellen White directly references John 8:56 in this passage.
"It was to impress Abraham's mind with the reality of the gospel, as well as to test his faith, that God commanded him to slay his son. The agony which he endured during the dark days of that fearful trial was permitted that he might understand from his own experience something of the greatness of the sacrifice made by the infinite God for man's redemption. No other test could have caused Abraham such torture of soul as did the offering of his son. God gave His Son to a death of agony and shame. The angels who witnessed the humiliation and soul anguish of the Son of God were not permitted to interpose, as in the case of Isaac. There was no voice to cry, “It is enough.” To save the fallen race, the King of glory yielded up His life. What stronger proof can be given of the infinite compassion and love of God? “He that spared not His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?” Romans 8:32 . PP 154.2"
"He that spared not his own Son, but delivered him up for us all, how shall he not with him also freely give us all things?"
Ellen White directly references Romans 8:32 in this passage.
"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. PP 154.3"
"For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men."
Both passages discuss the idea of events being observed by heavenly beings. EGW expands on the idea of the universe as a 'lesson book' in the context of the controversy between Christ and Satan, while 1 Corinthians 4:9 speaks of apostles as a spectacle to the world and angels. The connection is thematic, not a direct quote or principle, but meaningful.
