"For His disciples Christ prayed: “Sanctify them through Thy truth: Thy word is truth.” A pleasant, self- satisfied feeling is not an evidence of sanctification. A faithful record is kept of all the acts of the children of men. Nothing can be concealed from the eye of the high and holy One that inhabiteth eternity. Some make Christ ashamed of them by their devising and planning and scheming. God does not approve of their conduct, for the Lord Jesus is dishonored by their spirit and their works. They forget the words of the apostle: “We are made a spectacle unto the world, and to angels, and to men.” 1 Corinthians 4:9 . 8T 235.1"
"For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle unto the world, and to angels, and to men."
EGW directly quotes 1 Corinthians 4:9.
"Sanctify them through thy truth: thy word is truth."
EGW directly quotes John 17:17.
"The instruction that the Lord has given concerning His work points out the right way. God's plans and God's thoughts are as much higher than man's plans and man's thoughts as the heavens are higher than the earth. God's voice is to be heard, His wisdom is to guide. He has outlined His plan in His word and in the testimonies that He has sent to His people. That work only which is carried on in accordance with the principles of His word will stand fast forever. 8T 235.2"
"For my thoughts are not your thoughts, neither are your ways my ways, saith the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts."
EGW explicitly alludes to Isaiah 55:8-9, mirroring the language and concept of God's thoughts and ways being higher than man's.
"Thy word is a lamp unto my feet, and a light unto my path."
While not a direct quote, the EGW passage echoes the sentiment of Psalms 119:105 regarding the importance of God's word as a guide. The EGW passage speaks of God's plans and thoughts being higher than man's, and His word outlining His plan, which aligns with the idea of the Bible being a 'lamp' and 'light.'
