"Chapter 79—“It is Finished” Christ did not yield up His life till He had accomplished the work which He came to do, and with His parting breath He exclaimed, “It is finished.” John 19:30 . The battle had been won. His right hand and His holy arm had gotten Him the victory. As a Conqueror He planted His banner on the eternal heights. Was there not joy among the angels? All heaven triumphed in the Saviour's victory. Satan was defeated, and knew that his kingdom was lost. DA 758"
"When Jesus therefore had received the vinegar, he said, It is finished: and he bowed his head, and gave up the ghost."
EGW directly quotes John 19:30 ('It is finished') and elaborates on its significance, making it a clear explicit allusion.
"To the angels and the unfallen worlds the cry, “It is finished,” had a deep significance. It was for them as well as for us that the great work of redemption had been accomplished. They with us share the fruits of Christ's victory. DA 758.2"
"To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,"
Both passages discuss the impact of Christ's work on heavenly beings. Ephesians 3:10 speaks of making known God's wisdom to principalities and powers, while the EGW quote speaks of the significance of 'It is finished' to angels and unfallen worlds. The connection is thematic, focusing on the broader implications of redemption beyond humanity.
"Not until the death of Christ was the character of Satan clearly revealed to the angels or to the unfallen worlds. The archapostate had so clothed himself with deception that even holy beings had not understood his principles. They had not clearly seen the nature of his rebellion. DA 758.3"
"And no marvel; for Satan himself is transformed into an angel of light."
Both passages address Satan's deceptive nature. 2 Corinthians 11:14 explicitly states Satan transforms into an angel of light, while the EGW quote explains that Christ's death revealed Satan's character to the angels. The EGW quote amplifies the idea of Satan's deception, explaining why it was so effective.
"It was a being of wonderful power and glory that had set himself against God. Of Lucifer the Lord says, “Thou sealest up the sum, full of wisdom, and perfect in beauty.” Ezekiel 28:12 . Lucifer had been the covering cherub. He had stood in the light of God's presence. He had been the highest of all created beings, and had been foremost in revealing God's purposes to the universe. After he had sinned, his power to deceive was the more deceptive, and the unveiling of his character was the more difficult, because of the exalted position he had held with the Father. DA 758.4"
"Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord God; Thou sealest up the sum, full of wisdom, and perfect in beauty."
The EGW passage directly quotes Ezekiel 28:12 and explicitly identifies Lucifer with the figure described in the verse. This is a clear and direct allusion.
