"During the centuries immediately preceding the Flood, success had attended Satan's efforts to bring about a worldwide prevalence of rebellion against God. And even the lessons of the Deluge were not long held in remembrance. With artful insinuations Satan again led the children of men step by step into bold rebellion. Again he seemed about to triumph, but God's purpose for fallen man was not thus to be set aside. Through the posterity of faithful Abraham, of the line of Shem, a knowledge of Jehovah's beneficent designs was to be preserved for the benefit of future generations. From time to time divinely appointed messengers of truth were to be raised up to call attention to the meaning of the sacrificial ceremonies, and especially to the promise of Jehovah concerning the advent of the One toward whom all the ordinances of the sacrificial system pointed. Thus the world was to be kept from universal apostasy. PK 687.1"
"And God saw that the wickedness of man was great in the earth, and that every imagination of the thoughts of his heart was only evil continually."
Both passages discuss the widespread wickedness of humanity. EGW's passage refers to the rebellion against God before the Flood, while Genesis 6:5 describes the pervasive evil that prompted the Flood. The EGW passage amplifies the concept of widespread rebellion mentioned in Genesis.
"And God said unto Noah, The end of all flesh is come before me; for the earth is filled with violence through them; and, behold, I will destroy them with the earth."
Both passages relate to the corruption of humanity before the flood. Genesis 6:13 states God's intention to destroy the earth due to violence, while the EGW passage describes Satan's success in bringing about rebellion against God, leading to the Flood. The EGW passage provides context for the violence mentioned in Genesis.
"Not without the most determined opposition was the divine purpose carried out. In every way possible the enemy of truth and righteousness worked to cause the descendants of Abraham to forget their high and holy calling, and to turn aside to the worship of false gods. And often his efforts were all but successful. For centuries preceding Christ's first advent, darkness covered the earth, and gross darkness the people. Satan was throwing his hellish shadow athwart the pathway of men, that he might prevent them from gaining a knowledge of God and of the future world. Multitudes were sitting in the shadow of death. Their only hope was for this gloom to be lifted, that God might be revealed. PK 687.2"
"For, behold, the darkness shall cover the earth, and gross darkness the people: but the Lord shall arise upon thee, and his glory shall be seen upon thee."
The EGW passage directly echoes the language of Isaiah 60:2, specifically the phrase "darkness shall cover the earth, and gross darkness the people." This is a clear allusion to the Isaiah verse, used to describe the spiritual state of the world before Christ's first advent.
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Both passages describe a spiritual battle against evil forces. Ephesians 6:12 speaks of wrestling against spiritual wickedness, while the EGW passage describes Satan's opposition to God's purpose and his efforts to lead people astray. The EGW passage illustrates the specific ways in which this spiritual battle manifested itself.
"The people that walked in darkness have seen a great light: they that dwell in the land of the shadow of death, upon them hath the light shined."
Both passages describe a state of spiritual darkness and the hope for light. Isaiah 9:2 speaks of people walking in darkness and seeing a great light, while the EGW passage describes the darkness covering the earth before Christ's advent and the hope for God to be revealed. The EGW passage uses similar imagery to convey the spiritual condition of humanity.
