Here are several quotes from Ellen G. White's writings, outside of the Conflict of the Ages series, regarding the sanctifying truth of Jesus coming to earth as a human to die for us:
"Jesus was ‘the Word of God’—God's thought made audible. Not alone for His earthborn children was this revelation given. Our little world is the lesson book of the universe. Both redeemed and unfallen beings will find in the cross of Christ their science and their song. They will see that the glory shining in the face of Jesus is the glory of self-sacrificing love." (
HLv 11.2)
"Jesus was the majesty of heaven, the beloved commander of the angels, who delighted to do His pleasure. He was one with God, ‘in the bosom of the Father’ (John 1:18), yet He thought it not a thing to be desired to be equal with God while man was lost in sin and misery. He stepped down from His throne, He left His crown and royal scepter, and clothed His divinity with humanity. He humbled Himself even to the death of the cross, that man might be exalted to a seat with Him upon His throne." (1SM 321)
"The cross of Christ testifies to the immutability of the law of God—testifies that God so loved us that He gave His Son to die for our sins; but Christ came not to destroy but to fulfill the law. Not one jot or tittle of God's moral standard could be changed to meet man in his fallen condition. Jesus died that He might ascribe unto the repenting sinner His own righteousness, and make it possible for man to keep the law." (
1SM 312.2)
"Christ came to reveal to the sinner the justice and love of God, that He might give repentance to Israel and remission of sins. When the sinner beholds Jesus lifted up upon the cross, suffering the guilt of the transgressor, bearing the penalty of sin...he is led to repentance toward God because of his transgression of the law which is holy, and just, and good." (
1SM 324.1)
"Jesus came to suffer in our behalf, that He might impart to us His righteousness. There is but one way of escape for us, and that is found only in becoming partakers of the divine nature." (
3SM 197.2)
"The uplifted Saviour is to appear in His efficacious work as the Lamb slain, sitting upon the throne, to dispense the priceless covenant blessings, the benefits He died to purchase for every soul who should believe on Him... Centuries, ages, can never diminish the efficacy of this atoning sacrifice." (
TM 92.1)
"Our hard hearts need to be broken. We need to come together in perfect unity, and we need to realize that we are the purchase of the blood of Jesus Christ of Nazareth. Let each one say: 'He gave His life for me, and He wants me, as I go through this world, to reveal the love that He revealed in giving Himself for me.'" (
CCh 290.3)
