"Thus God's people, exposed to the deceptive power and unsleeping malice of the prince of darkness, and in conflict with all the forces of evil, are assured of the unceasing guardianship of heavenly angels. Nor is such assurance given without need. If God has granted to His children promise of grace and protection, it is because there are mighty agencies of evil to be met—agencies numerous, determined, and untiring, of whose malignity and power none can safely be ignorant or unheeding. GC 513.1"
"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 acknowledge the existence of spiritual warfare against evil forces. Ephesians 6:12 describes the nature of the enemy, while EGW emphasizes the need for divine protection in this conflict.
"For he shall give his angels charge over thee, to keep thee in all thy ways."
Both passages discuss the protection of God's people through angels. Psalm 91:11 is a general promise, while EGW provides a broader context of spiritual warfare and the need for such protection.
"Evil spirits, in the beginning created sinless, were equal in nature, power, and glory with the holy beings that are now God's messengers. But fallen through sin, they are leagued together for the dishonor of God and the destruction of men. United with Satan in his rebellion, and with him cast out from heaven, they have, through all succeeding ages, co-operated with him in his warfare against the divine authority. We are told in Scripture of their confederacy and government, of their various orders, of their intelligence and subtlety, and of their malicious designs against the peace and happiness of men. GC 513.2"
"For if God spared not the angels that sinned, but cast them down to hell, and delivered them into chains of darkness, to be reserved unto judgment;"
Both passages discuss the fall of angels and their subsequent punishment. EGW expands on the idea presented in 2 Peter 2:4, providing more detail about the nature and purpose of these fallen angels.
"Old Testament history presents occasional mention of their existence and agency; but it was during the time when Christ was upon the earth that evil spirits manifested their power in the most striking manner. Christ had come to enter upon the plan devised for man's redemption, and Satan determined to assert his right to control the world. He had succeeded in establishing idolatry in every part of the earth except the land of Palestine. To the only land that had not fully yielded to the tempter's sway, Christ came to shed upon the people the light of heaven. Here two rival powers claimed supremacy. Jesus was stretching out His arms of love, inviting all who would to find pardon and peace in Him. The hosts of darkness saw that they did not possess unlimited control, and they understood that if Christ's mission should be successful, their rule was soon to end. Satan raged like a chained lion and defiantly exhibited his power over the bodies as well as the souls of men. GC 513.3"
"Then was Jesus led up of the Spirit into the wilderness to be tempted of the devil. And when he had fasted forty days and forty nights, he was afterward an hungred. And when the tempter came to him, he said, If thou be the Son of God, command that these stones be made bread. But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God. Then the devil taketh him up into the holy city, and setteth him on a pinnacle of the temple, And saith unto him, If thou be the Son of God, cast thyself down: for it is written, He shall give his angels charge concerning thee: and in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone. Jesus said unto him, It is written again, Thou shalt not tempt the Lord thy God. Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them; And saith unto him, All these things will I give thee, if thou wilt fall down and worship me. Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. Then the devil leaveth him, and, behold, angels came and ministered unto him."
Both passages describe the conflict between Christ and Satan. Matthew 4:1-11 recounts the temptation of Christ, while EGW describes Satan's efforts to maintain control over the world during Christ's ministry. The EGW passage amplifies the broader context of the conflict illustrated in Matthew.
