"There are Christians who think and speak altogether too much about the power of Satan. They think of their adversary, they pray about him, they talk about him, and he looms up greater and greater in their imagination. It is true that Satan is a powerful being; but, thank God, we have a mighty Saviour, who cast out the evil one from heaven. Satan is pleased when we magnify his power. Why not talk of Jesus? Why not magnify His power and His love? DA 493.1"
"I can do all things through Christ which strengtheneth me."
While not a direct quote, the EGW passage's emphasis on focusing on the power of Christ rather than the power of Satan aligns with the general theme of Philippians 4:13, which speaks of strength through Christ. It's a thematic parallel in that both passages encourage reliance on divine power over focusing on limitations or opposition.
"The rainbow of promise encircling the throne on high is an everlasting testimony that “God so loved the world, that He gave His only-begotten Son, that whosoever believeth in Him should not perish, but have everlasting life.” John 3:16 . It testifies to the universe that God will never forsake His people in their struggle with evil. It is an assurance to us of strength and protection as long as the throne itself shall endure. DA 493.2"
"For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."
Ellen White directly references John 3:16 in this passage.
