"In the region of Caesarea Philippi, Christ was out of the reach of Herod and Caiaphas, the disciples reasoned. He had nothing to fear from the hatred of the Jews or from the power of the Romans. Why not work there, at a distance from the Pharisees? Why need He give Himself up to death? If He was to die, how was it that His kingdom was to be established so firmly that the gates of hell should not prevail against it? To the disciples this was indeed a mystery. DA 418.1"
"And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it."
The EGW passage directly references and interprets Matthew 16:18, specifically the phrase "the gates of hell shall not prevail against it," within the context of the disciples' misunderstanding of Jesus's mission.
"They were even now journeying along the shores of the Sea of Galilee toward the city where all their hopes were to be crushed. They dared not remonstrate with Christ, but they talked together in low, sorrowful tones in regard to what the future would be. Even amid their questionings they clung to the thought that some unforeseen circumstance might avert the doom which seemed to await their Lord. Thus they sorrowed and doubted, hoped and feared, for six long, gloomy days. DA 418.2"
"Saying, The Son of man must suffer many things, and be rejected of the elders and chief priests and scribes, and be slain, and be raised the third day."
The EGW passage describes the disciples' sorrow and doubt regarding Jesus' impending suffering, which aligns with the prediction of his suffering in Luke 9:22. While not a direct quote, the shared theme of the disciples' reaction to Jesus' prediction makes the connection meaningful.
