"We should carefully examine our ways and our spirit, and see in what manner we are doing the work given us of God, which involves the destiny of souls. The very highest obligation is resting upon us. Satan is standing ready, burning with zeal to inspire the whole confederacy of satanic agencies, that he may cause them to unite with evil men and bring upon the believers of truth speedy and severe suffering. Every unwise word that is uttered through our brethren will be treasured up by the prince of darkness. 9T 241.2"
"Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:"
Both passages highlight the vigilance needed against Satan's influence and his desire to harm believers. The EGW passage expands on the idea of Satan using human actions (unwise words) to achieve his goals, while 1 Peter 5:8 focuses on his predatory nature.
