"good and make as attractive as possible. All who are thus ensnared will learn at a dreadful expense the folly of selling heaven and immortality for a deception that is fatal in its consequences. Our adversary, the devil, is not void of wisdom or strength. He goeth about like a roaring lion, seeking whom he may devour. He will work “with all power and signs and lying wonders, and with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.” Because they rejected the truth, “God shall send them strong delusion, that they should believe a lie: that they all might be damned who believed not the truth, but had pleasure in unrighteousness.” We have a powerful, deceptive foe with whom to contend, and our only safety is in Him who is to come, who will consume this archdeceiver with the spirit of His mouth, and destroy with the brightness of His coming. 2T 172.2"
"Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:"
EGW directly quotes and alludes to 1 Peter 5:8, using the phrase "goeth about like a roaring lion, seeking whom he may devour." This is a clear and direct reference.
