"Skepticism could not deny the existence of Eden while it stood just in sight, its entrance barred by watching angels. The order of creation, the object of the garden, the history of its two trees so closely connected with man's destiny, were undisputed facts. And the existence and supreme authority of God, the obligation of His law, were truths which men were slow to question while Adam was among them. PP 84.1"
"So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life."
This passage also refers to the cherubim guarding Eden, directly alluding to Genesis 3:24. While it focuses on the implications of this fact for skepticism, the reference to the cherubim is undeniable.
"Notwithstanding the prevailing iniquity, there was a line of holy men who, elevated and ennobled by communion with God, lived as in the companionship of heaven. They were men of massive intellect, of wonderful attainments. They had a great and holy mission—to develop a character of righteousness, to teach a lesson of godliness, not only to the men of their time, but for future generations. Only a few of the most prominent are mentioned in the Scriptures; but all through the ages God had faithful witnesses, truehearted worshipers. PP 84.2"
"By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh. By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God. But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him. By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith."
Both passages discuss a line of righteous individuals who maintained their faith despite prevailing iniquity. Hebrews 11 provides specific examples (Abel, Enoch, Noah), while EGW speaks more generally of faithful witnesses throughout the ages. The theme of faithful individuals standing apart is present in both.
Of Enoch it is written that he lived sixty-five years, and begat a son. After that he walked with God three hundred years. During these earlier years Enoch had loved and feared God and had kept His commandments. He was one of the holy line, the preservers of the true faith, the progenitors of the promised seed. From the lips of Adam he had learned the dark story of the Fall, and the cheering one of God's grace as seen in the promise; and he relied upon the Redeemer to come. But after the birth of his first son, Enoch reached a higher experience; he was drawn into a closer relationship with God. He realized more fully his own obligations and responsibility as a son of God. And as he saw the child's love for its father, its simple trust in his protection; as he felt the deep, yearning tenderness of his own heart for that first-born son, he learned a precious lesson of the wonderful love of God to men in the gift of His Son, and the confidence which the children of God may repose in their…
"And Enoch walked with God after he begat Methuselah three hundred years, and begat sons and daughters:"
The EGW passage directly references Enoch's age when he begat Methuselah and the fact that he walked with God for 300 years, which is explicitly stated in Genesis 5:22. It then expands on the nature of that walk with God.
