"***** Chapter 75—Walk in the Light I was shown that God's people dwell too much under a cloud. It is not His will that they should live in unbelief. Jesus is light, and in Him is no darkness at all. His children are the children of light. They are renewed in His image, and called out of darkness into His marvelous light. He is the light of the world, and so also are they that follow Him. They shall not walk in darkness, but shall have the light of life. The more closely the people of God strive to imitate Christ, the more perseveringly will they be pursued by the enemy; but their nearness to Christ strengthens them to resist the efforts of our wily foe to draw them from Christ. 1T 405"
"Then spake Jesus again unto them, saying, I am the light of the world: he that followeth me shall not walk in darkness, but shall have the light of life."
EGW uses the phrase 'light of the world' and 'shall not walk in darkness, but shall have the light of life' which are direct allusions to John 8:12.
"This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all."
EGW directly references the concept of God being light and no darkness being in Him, which is a direct allusion to 1 John 1:5.
"For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:"
EGW uses the phrase 'children of light' and the concept of walking as children of light, which is a direct allusion to Ephesians 5:8.
