"John was cast into a caldron of boiling oil; but the Lord preserved the life of His faithful servant, even as He preserved the three Hebrews in the fiery furnace. As the words were spoken, Thus perish all who believe in that deceiver, Jesus Christ of Nazareth, John declared, My Master patiently submitted to all that Satan and his angels could devise to humiliate and torture Him. He gave His life to save the world. I am honored in being permitted to suffer for His sake. I am a weak, sinful man. Christ was holy, harmless, undefiled. He did no sin, neither was guile found in His mouth. AA 570.1"
"He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the form of the fourth is like the Son of God."
The EGW passage explicitly alludes to the story of the three Hebrews in the fiery furnace as a parallel to John's preservation in the boiling oil. The original confidence is maintained.
"Who did no sin, neither was guile found in his mouth:"
The EGW passage directly quotes the phrase 'He did no sin, neither was guile found in his mouth,' which is a direct allusion to 1 Peter 2:22. The relation type is changed to explicit_allusion and the confidence is increased.
"And they departed from the presence of the council, rejoicing that they were counted worthy to suffer shame for his name."
The EGW passage describes John's willingness to suffer for Christ's sake, which thematically parallels the rejoicing of the apostles in Acts 5:41 for being counted worthy to suffer for His name. The confidence is slightly increased.
"Again the hand of persecution fell heavily upon the apostle. By the emperor's decree John was banished to the Isle of Patmos, condemned “for the word of God, and for the testimony of Jesus Christ.” Revelation 1:9 . Here, his enemies thought, his influence would no longer be felt, and he must finally die of hardship and distress. AA 570.3"
"I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ."
Ellen White directly references Revelation 1:9 in this passage.
"Patmos, a barren, rocky island in the Aegean Sea, had been chosen by the Roman government as a place of banishment for criminals; but to the servant of God this gloomy abode became the gate of heaven. Here, shut away from the busy scenes of life, and from the active labors of former years, he had the companionship of God and Christ and the heavenly angels, and from them he received instruction for the church for all future time. The events that would take place in the closing scenes of this earth's history were outlined before him; and there he wrote out the visions he received from God. When his voice could no longer testify to the One whom he loved and served, the messages given him on that barren coast were to go forth as a lamp that burneth, declaring the sure purpose of the Lord concerning every nation on the earth. AA 570.4"
"I John, who also am your brother, and companion in tribulation, and in the kingdom and patience of Jesus Christ, was in the isle that is called Patmos, for the word of God, and for the testimony of Jesus Christ."
The EGW passage directly references John's presence on Patmos and the circumstances surrounding his exile, as described in Revelation 1:9. It expands upon the biblical account by adding details about the island's nature and the spiritual experiences John had there.
